In this post, I explore torch - a package for R that mirrors the PyTorch framework for deep learning. Motivation I’ve been a bit reluctant to join in on the deep learning hype for some time. Much of this I attribute to my lack of enthusiasm toward Pyth... [Read more...]

Very often I find myself in a situation where I need to perform the same operation on multiple columns in a data set. For this, I turn to none other than dplyr’s across function. But as we’ll see, not only does across help when we are interactively wra... [Read more...]

In psychology, we increasingly encounter data that is nested. It is to the point now where any quantitative psychologist worth their salt must know how to analyze multilevel data. A common approach to multilevel modeling is the varying effects approach... [Read more...]
