Naive Bayes classifiers are simple but powerful tools for classification in statistics and machine learning. In this video tutorial, I use a simulated data set and illustrate the mathematical details...continue reading.
I am so grateful to Mandy Gu for being a guest on The Central Equilibrium to talk about word embeddings and text classification. She began by showing how data from...continue reading.
Most SAS procedures require the RUN; statement to signal their termination. However, there are some notable exceptions to this. I have written about PROC SQL many times on my blog,...continue reading.
I am pleased to welcome Arnab Chakraborty back to my talk show, “The Central Equilibrium“, to talk about the Monty Hall Problem and Bayes’ theorem. In this episode, he shows...continue reading.
I am so pleased to publish this new episode of “The Central Equilibrium“, featuring Benjamin Garden. He talked about simple and compound interest in the context of finance and investment,...continue reading.
I am excited to present the first of a multi-episode series on neural networks on my talk show, “The Central Equilibrium”. My guest in this series in Layne Newhouse, and...continue reading.
In SAS, you can perform PROC TTEST for multiple numeric variables in the same procedure. Here is an example using the built-in data set SASHELP.BASEBALL; I will compare the number...continue reading.
I will speak on the career-advice panel at the 2018 Canadian Statistics Student Conference. It will be held on Saturday, June 2, at McGill University. If you will attend this...continue reading.
In a recent blog post, I introduced an easy and efficient way to create indicator variables from categorical variables in SAS. This method pretends to run logistic regression, but it...continue reading.
Introduction In statistics and biostatistics, the creation of binary indicators is a very useful practice. They can be useful predictor variables in statistical models. They can reduce the amount of...continue reading.
