Hi! I am going to Concordia’s Oktoberfest for the first time on Friday in the tent. What are some good tips to know? Is there food? Is everything cash only?

Thanks in advance!

I now have two DataFrames. One is called returns , which contains data starting from 2001 with a shape of (5100, 5000). The other is called cs, which has a similar structure to returns but starts from 2007, with a shape of (2000, 5000).

The cs DataFrame represents event data: if there’s an event, the value is 1; otherwise, it’s NaN.

Now, I’d like to perform an event study to analyze how cross-sectional return dispersion behaves before and after earnings announcements. Specifically, I want to visualize the pattern of volatility (i.e., cross-sectional dispersion) from –2 days to +2 days around the event date. The x-axis should represent days relative to the event (–2 to +2), and the y-axis should represent volatility (dispersion)

Then i had the codes like this:

import pandas as pd

import numpy as np

import matplotlib.pyplot as plt

returns_aligned = returns.loc[cs.index]

daily_volatility = returns_aligned.std(axis=1)

event_dates = cs.dropna(how='all').index

window_days = [-2, -1, 0, 1, 2]

volatility_pattern = []

for day in window_days:

day_volatilities = []

for event_date in event_dates:

target_date = event_date + pd.Timedelta(days=day)

if target_date in daily_volatility.index:

day_volatilities.append(daily_volatility[target_date])

if day_volatilities:

avg_vol = np.mean(day_volatilities)

volatility_pattern.append(avg_vol)

else:

volatility_pattern.append(0)

I expected the plot is like a V shape, but it turns out an upward line..

Who can tell me whats wrong with the code...

Hey all, taking the Flixbus to Pearson soon and haven't done this in a year or so. I used to always get on at the bus stop at King and Victoria, but now the website (www.flixbus.ca/bus/kitchener-on) says Weber and Victoria. All the Reddit and Facebook threads I could find were at least 4 weeks old, and almost all said that the stop is King/Victoria, but 1 comment from 4 weeks ago said it's at Weber/Victoria now.

Could someone who's taken the bus in the past 4w please confirm? And point me to where the stop is exactly, in case the website is incorrect? (Website says "Bus shelter at Weber St. West and Victoria St. North".) Thanks!

Our mean for the math 136 MT was a 57 with a median of 60. Isn’t that a little low?

Looking for some new work pants. I tend to lean more towards one that are more of a fabric material or stretchy. Rather than the more traditional work pant material for pants that are less stretchy/more restrictive. I wear petite length clothing, but can also alter regular length pants. Also, not against thrifting or new ones. Although, I haven’t had much luck in the area with thrift stores for work pants, but I could be going to the wrong places.

I fell asleep last night with my laptop on and still logged into the Waterloo Learn site.
When I woke up, I kept getting a 403 error.

I tried clearing cookies, removing my VPN, and even resetting the network using ipconfig.
Tried using incognito mode same issue. Switched browsers same issue.

No matter what I do, it keeps showing 403 Forbidden. The only time it works is when I turn VPN on.

Does anyone know how to fix this?

There was a car accident last night in Kitchener in front of my house and I ran from my backyard to help him. The car was rotated and airbag was deployed so we couldn't open the door . I understand 911 was coming so everyone was waiting for them. Now when I look on the side walk I see lots of people doing Facebook live or something live , recording the whole thing . and the guy was still inside the car sweating. WTF is wrong with these people. Is this the new norm that to record everything what you see even if it's serious or critical condition to get some views. I know we can't help that much but I feel recording is morally not right in these situation. I don't know what the group thinks but if you can't help, Don't record .

Anyone taken this course, what's the topic for the written assignment? I just want to get a head start.

Heyy.. so I am a high school student and deciding which course to do before applying next month or 2. So far I might have maybe just maybe over planned but totally open to change if needed. I am trying to shortlist my options and want to know what's worth. I would love to hear from people who are doing this courses or might be open to them. 📝Legal Studies 📝 Public Health & psychology as minor 📝 Health Sciences & Cognitive Science as minor 📝 Public Health & psychology as minor I still haven't decided if I wanna go to Waterloo or not but I got in then yea.. open to different perspectives from yall🍯

I'm talking ones that require actual ML knowledge like Tensorflow/Pytorch, and not Javascript/React with a generic "MuSt HaVe In DePtH kNoWlEdGe Of Ml PrInCiPlEs" at the bottom. Like out of the few ML jobs there are, 80% of them sound like glorified full-stack developers. Isn't ML supposed to be the future or something?

Any family doctor accepting new patients in Kitchener region ? Thanks for suggestions

We toured AVM Kitchener and are very interested in sending our son there. Anyone have their kids there? We had a wonderful tour and loved the space, anyone have feedback?

Hi, I'm a first year and was in the Chem 120L class with Sue. I have a very uncooperative lab partner, and was about to start my 1st lab report. Is the marking for post lab reports lenient or tough? Should the lab report be extensively heavy with too much info that may or may not correspond with the question asked? Feel free to share any additional tips for anything related to labs. Thanks!

helloo, I am taking the course online rn and I am so stressed for the exam especialy about the content in textbook..

On Saturday, October, 11, I left my wagon propped up against the back of the building at 44 Gaukel street while I was unloading some items. I stupidly forgot it there and after going back to find it, of course it was gone. It’s the black and blue costco wagon, but it’s got a special push handle/bar that I installed two summers ago as well as a velcro strap with a hook hanging off of the handle bar. As a small business owner, I depend on this wagon for setting up at markets and as a single parent, I typically use it to cart my toddler around. The wagon has honestly been such a blessing for us, if you found it or know someone who found it, I would really love to have it back :(

Does anyone know of who does bird grooming (not exotic wings and things) in the Kitchener / Waterloo area?

I used to go to impact training centre when they had open gym from morning to night and pay 10$ to get in, is there anything like that, that I could go to?

THANK YOU FOR YOUR ATTENTION

Sorry i seem like a beg rn (which i am rn actually) but if anybody is free to help a sleep deprived anxious first year about the ciip project please dm me!!!!!

My wallet and car keys fell out of my diaper bag at Concordia yesterday. There’s no of real value in the wallet except IDs and my kids health cards. I’ve filed a police report and notified Concordia - but so far they haven’t turned up. There have been no attempts to use the debit cards either.

If anyone saw them or turned them in somewhere , I would be so grateful.

I thought it was odd this white duck just chills in Galt. Chatgpt says the white one is more likely a domesticated duck someone released. I dunno how accurate that is. But hes cute!

if anyone has any info on the bu111 midterm marks this year or even in previous years i’d love to hear it so i know what to expect

My family and I (with 2 young children) are moving to the Westmount area and I’m looking for any feedback people have with the area/neighbourhood around Westmount PS. Or even better - of the school itself? I’m so anxious about relocating from the GTA suburbs and mostly just hope it’s a nice community that will be easy to fit in and make friends as a young family.

I keep seeing people post stories of being taken advantage of by a contractor, and we hear them from clients daily. We feel an amazing purpose in helping homeowners avoid scams and shutting down these scammers for good. So far we've helped 100's avoid scams and successfully shut down almost a dozen scam contractors. It's my pride and joy to protect Canadians and make Canada a safer place. Big thanks to Cambridge Today for featuring BetterBid and our mission to protect Canadians from renovation scams. Stay safe out there.

Literally does a U turn from the far right lane. Absolutely ridiculous and dangerous.

Unfortunately nothing new.

Thought y'all should check it out. Pretty good deal, IMO.

Edit: Works even for recently graduated ppl!

I live on king and occasionally like to eat there if I'm lazy but don't want unhealthy takeout and I was curious if you can use the pool table. My friend comes down to stay with me sometimes and we used to play a lot before I moved here.

I graduated with a bachelor of science this spring but have had zero success finding a job the past few months. I’ve recently made the decision to switch over to look for part time positions unrelated to my degree, but SURPRISE, also no luck here either:)

Was wondering if seasonal retail positions typically start to get posted soon? Knowing this would give me a little bit of hope for my future.

Ik the job market is really rough right now, good luck to anyone else in the same shoes as me!

I have to travel to Toronto for work on Tuesday, Wednesday and Thursday. I wish I didn’t have to but I don’t have a choice.

Looking for anyone to share group pass. I got the link to the WhatsApp group but the request is still pending.

If you are interested, dm me. We can work out the details.

Thanks.
