In this category you will find posts that are related to programming and should be interesting for psychologists, cognitive scientists, and neuroscientists. Well, almost every researcher would probably find some of the information useful at some time!

Every research psychologist, cognitive scientist, and neuroscientist, should know how to program.. Knowing how to program and write scripts will make many of a researchers everyday tasks much easier. For instance, instead of going through line after line of raw data you can write a Python script that runs through each cell in each column. Furthermore, you get the possibility to use more advanced, and cutting edge, statistical techniques by using R statistical programming environment.

Another example might be to create experiments using PsychoPy (either by coding using Python or using the drag-and-drop interface) and the cheap and open-source Arduino microcontroller. Also, coding is fun and relaxing!

Extract P-Values from lm() in R: Empower Your Data Analysis

2 Comments / Programming, R / By

In this blog post, we will learn how to extract P-values from the regression models in R. We will explore the process of fitting a regression model, and then dive into the methods of extracting P-values using the lm() function. Additionally, we will demonstrate how to extract P-values from all predictors and leverage the tidy() function for a tidy output. Unlock the power of statistical inference with the ability to extract P-values from lm() in R.
