Linear Regression in R
R presents various ways to carry out linear regressions. The most natural way is to use the lm() function, the R build-in OLS estimator. In this post I will present you how to use lm() and run OLS on the following model
Construct the OLS estimator as a function in R
This post shows how to manually construct the OLS estimator in R (see this post for the exact mathematical derivation of the OLS estimator). In contrary to a previous post, this post focuses on setting up the OLS estimator as a R function. While the aim of the former post was much more on the construction of the OLS estimator in general, is this post all about constructing a functional form around the estimator. Continue reading Construct the OLS estimator as a function in R
Calculate OLS estimator manually in R
This post shows how to manually construct the OLS estimator in R (see this post for the exact mathematical derivation of the OLS estimator). The code will go through each single step of the calculation and estimate the coefficients, standard errors and p-values. In case you are interested the coding an OLS function rather than in the step wise calculation of the estimation itself I recommend you to have a look at this post. Continue reading Calculate OLS estimator manually in R
How to Enable Gui Root Login in Debian 8
In this post I am going to explain how to enable GUI root access on Debian 8. Instructions for Debian 9 a similar and can be found here. At this point I should warn you that using the root account is dangerous as you can ruin your whole system. Try to follow this guide exactly.
