In this post we will discuss how to manually implement a Difference-in-Differences (DiD) estimator in R, using simulated data.

The sigmoid package makes it easy to become familiar with the way neural networks work by demonstrating the key concepts using straightforward code examples.

This is an example of how to build a Recurrent Neural Network in R.

Below is an example of how to handcode a logit model.

In this post we will discuss how to manually implement a Difference-in-Differences (DiD) estimator in R, using simulated data.

The most basic panel estimation is the Pooled OLS model, this model combines all data across indices and performs a regular Ordinary Least Squares Estimation.

Some simulated data, borrowed from this post.

In this short post I want to quickly demonstrate how the most basic neural network (no hidden layer) gives us the same results as the linear model.

The wiod package is now available on CRAN. The package contains the complete WIOD data sets, in a format compatible with the decompr and gvc package.

In yesterday’s post we developed a method for constructing a multivariate linear model with an intercept.

In order to understand statistics, you have to do the calculations yourself!

A new R package diagonals is now available on CRAN. The package implements several tools for dealing with fat diagonals on matrices, such as this one:

Quick experiment on embedding plot.ly graphics.

A typical example in which diagonals can be helpful is Social Network Analysis. For example, if we use matrices to represent friendship perceptions between i...
