Sharpen your data science skills with this is a hands-on workshop on stochastic processes
What is a stochastic processes? The word stochastic is jargon for random. A stochastic process is a system which evolves in time while undergoing chance fluctuations. We can describe such a system by defining a family of random variables,
In this workshop, we will talk about a variety of stochastic process models, give their definitions. We will discuss the underlying assumptions and theory for the models. Then we will then explore what types of problems they solve for and practical applications where they are used. This course will cover the following stochastic process models, Markov Chain, Random Walk, Poisson Process, Birth-and-Death Process, Branching Process, and Brownian Motion.
The workshop is designed to be hands-on. Participants are required to bring laptops and be ready to write R, analyze data and interpret results. For each model, we present an example with a complete R code, and then an exercise to work on. Workshop participants do not need to be experts in R, the exercises generally require you to run a few functions that are given in the example problem.
The material covered by the workshop will be taken from my recently published book Stochastic Processes with R, CRC Press, 2022.
Dr. Olga Korosteleva, is a professor of Statistics at the Department of Mathematics and Statistics at California State University, Long Beach (CSULB). She received her Bachelor’s degree in Mathematics in 1996 from Wayne State University in Detroit, and a Ph.D. in Statistics from Purdue University in West Lafayette, Indiana, in 2002. Since then she has been teaching mostly Statistics courses in the Master’s program in Applied Statistics at CSULB, and loving it!
Dr. Olga is an undergraduate advisor for students majoring in Mathematics with an option in Statistics. She is also the faculty supervisor for the Statistics Student Association. She is also the immediate past-president of the Southern California Chapter of the American Statistical Association (SCASA). Dr. Olga is the editor-in-chief of SCASA’s monthly eNewsletter and the author (co-author) of five statistical books.

SoCal RUG GitHub Repo: https://github.com/socalrug/
Please install git and clone the following repo before the event. Pull before the start of the event
command:
git clone https://github.com/socalrug/stochastic_processes_2023-02-11.git
Event Repo: https://github.com/socalrug/stochastic_processes_2023-02-11
An alternative approach if you are not comfortable with git is to download a zip file of the repo. However, this approach requires you to download it each time there is a change.
A slack channel has been set up for the event. This will be used for general announcements but it is also a great source for you to ask questions to other participants.
If you have not created an account on our slack group, create one using the following link:

The channel for the course is stochastic-2023
Since this event depends on you have an R setup that is functional with the correct packages and version of R, we highly recommend that you run the check_setup.r before the event. If you have issues, please reach out to us in the slack channel (see above) to get help.
You could use the Posit Cloud during the course instead of setting up RStudio and GitHub. There is a Posit project which will allow you to run RStudio in the cloud. It is preconfigured with the example and exercise code. Plus, it has all the required packages installed. You will need a Posit Cloud account. A free account can be set up.
Please follow us on twitter, oc_rug, and also tweet about the event with the hash tag #SoCalRUG
