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

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.

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.

function that draws random numbers and specify the Gamma distribution by using the `Gamma(a,b)`

command. The parameters a and b define the shape parameters of the Gamma distribution. This article provides a more generic overview of how to generate random numbers in Julia.

How can one save objects in Julia? One easy way to do so it to use the `JLD`

package. The following examples demonstrates how to save data objects in Julia and how to load the once they are saved.
