Julia presents various ways to carry out linear regressions. In this previous post, I explained how to run linear regression in Julia using the function linreg(). Unfortunately, linreg() is deprecated and no longer exists in Julia v1.0.
In this post I will present how to use the native function of Julia to run OLS on the following model

This blog post explains the difference between confidence intervals that use the t-distribution and confidence intervals that use the Normal distribution. Thereby, the post will not focus on the theoretical/mathematical differences of the two distributions, but rather compare the two types of confidence intervals using simulation studies. Furthermore, in case you are interested in replicating the presented results or simply play around with it yourself, I provide the R code to conduct the simulation exercises and to replicate the figures.

In this post, I am going to explain how to upgrade Debian 9 to Debian 10. You can enter the following eight steps in your terminal:

In this post I am going to explain how to enable GUI root access on Debian 10. It is very similar to enabling Gui Root Login in Debian 8 and to enabling Gui Root Login in Debian 9. 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.

In this post, I will show how one can easily construct confidence intervals in R. Assume you have a vector of numbers and you want to construct a confidence interval around the mean of this vector. The subsequent R code shows one easy way to calculate the confidence interval around the mean of this vector. The following code loads a function that allows you to pass on the vector and returns the confidence intervals. Per default the function returns the 95% confidence interval. However, the parameter ‘conf_level’ allows you to specify the interval you want. Furthermore, if you do not have many observations, you may want to use Student’s t-distribution instead of the Normal distribution. The Student’s t-distribution has wider tales when the number of observations is low and gives a you more conservative estimates of your confidence interval. In case you want to use Student’s t-distribution you case set the parameter ‘distribution’, i.e. distribution=”normal”.

How can we illustrate the dynamics of Keynesian Economics within an aggregate supply – aggregate demand (ASAD) framework? The following post explains the Keynesian dynamics that we discussed in a previous post using an AS-AD model.

One year ago, my blog reached the minimum traffic requirement of WordAds and the advertising platform added my blog to their program. Starting October 2017, I was able to display ads on my blog and earn part of the generated income. At the beginning, I was very excited. However, after few enthusiastic months, I soon realized that I will not be able to earn lots of money using WordAds. Sure, displaying adds earns some money, but compared to my regular salary, it is negligible.
