Scicloj Workshop: (Rescheduled)Introduction to the measures of statistical inference

Re-posting the older topic since I felt sick prior to the previous scheduled date. Apologies to all who signed in, hopefully second time is a charm.

Useful inferential statistics does not have to be just the domain of data scientists. This workshop follows examples in the book Statistics is Easy by Dennis Shasha and Manda Wilson, along with other real world examples to demonstrate concepts of fairness, p-value, confidence intervals, power. All concepts will be explained purely using functions from the core clojure library.

Few people remember statistics and often have to refer to books to apply formulae, hoping that the underlying distribution and its assumptions satisfy the needs of the formula, however the magic and the assumptions can be made concrete and clear by using randomization techniques collectively known as resampling.

In the workshop, we will simulate an experiment and analyze it statistically, answering the following questions: how accurate is the measurement likely to be (confidence interval), and could it have happened by mistake?

I currently work at Barracuda Networks as a Principal Engineer, working on platforms that collect store and make over 100 million emails searchable everyday.

Workshop Length & Structure:

• Two sessions 45 minutes each.
• The first session(05/07/2022 9 AM PST) will cover experiments used to understand significance tests most commonly used for AB experiments where an A is the normal occurring pattern and B is the observed pattern. We are trying to answer the question is B significantly different from A. We will talk about p-values in depth and look at some practical examples
• The second session (05/22/2022 9 AM PST) will include experiments that compare two groups to determine where each group has a range of values. In addition to saying whether the groups are significantly different from each other we will try to understand the measure of the difference between the groups(confidence intervals) and concepts of false positives(power). If time permits we can talk about other practical considerations such as outliers.

Where?

• Workshops will be held on Zoom
• We will use a thread on Zulip for chat

Very hopeful about this new Scicloj series of workshops organized by @ethanmiller @elenam @kiramclean @jsa-aerial @rohit and others.

A statistics workshop by Rohit is a great way to begin (really liked the last time he taught something similar).

Not too late to join and help in shaping the culture of this series!

@SK500 @Gabriele_Simeone @oxalorg @nandajavarma @gleenn @Sree_Charan you may like this rescheduled event on the coming weekend.

Hello Workshop Participants!

Really looking forward to the workshop tomorrow. As a reminder, the workshop will take place tomorrow, Saturday, May 7th, @ 9:00am PDT. To see what that will be in your time zone you can go here.

Please note that the event will take place on Zoom, moderated by Elena Machasova. We will use a Zulip topic for conversation, so we encourage you to sign up for Clojurians Zulip if you are not already.

Here are details for joining the event:

See you soon!

Hi All, the second part of Rohitâ€™s workshop â€śIntroduction to the measure of statistical inferenceâ€ť will take place this weekend, Sunday May 22nd @ 9:00am PDT (see the time your timezone here).

In this session, Rohit will continue his illustration of basic statistical concepts, this time with a focus on the statistical analysis of experiments with two groups.

We will post a zoom link for the session, 24-hours prior to the event, so stay tuned!
