Splines provide a useful way to model relationships that are more complex than a simple linear function. They work with a variety of regression models.

Member Training: Introduction to Data Analysis using R Tutorial
June 12th, 2025 by TAF Support
This month we are featuring a 9-module software tutorial by Kim Love: An Introduction to Data Analysis using R.
It’s perfect for people who:
- have never used R before
- need to refresh their R skills after not using it for while
- have figured out R on their own and would like a more systematic tutorial
Member Training: Interpreting (Even Tricky) Regression Coefficients Workshop
April 1st, 2025 by Karen Grace-Martin
In April and May, we’re doing something new: including in membership the workshop Interpreting (Even Tricky) Regression Coefficients with Karen Grace-Martin.
We’ll be releasing the first 3 of 6 modules in April and modules 4-6 in May and holding a special Q&A with Karen at the end of each month.
If you’ve ever wanted to know how to interpret your results or set up your model to get the information you needed, you’ll love this workshop.
Although it’s at Stage 2 and focuses entirely on linear models, everything applies to all sorts of regression models — logistic, multilevel, count models. All of them.

Member Training: Introduction to Binary Logistic Regression
December 3rd, 2024 by TAF Support
Binary logistic regression is one of the most useful regression models. It allows you to predict, classify, or understand explanatory relationships between a set of predictors and a binary outcome.

Member Training: Introduction to Item Response Theory and Rasch Models
November 1st, 2024 by TAF Support
How do you know if the items of a test are hard or easy; fair or biased; accurate at measuring ability or not?
Item Response Theory (IRT).
In this training, you will see, with real life examples, how IRT answers these questions to assess a test.
