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

In Julia, one can generate random numbers that follow a Gamma distribution by using the Distribution package. Thereby one can use the
rand() 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.

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

In Julia, you can set a seed to the random number generator using the

srand() function. The code example below sets the seed to 1234. Generating a random variable with
rand(1) after setting the seed to 1234 will always generate the same number, i.e. it will always return 0.5908446386657102.
Julia presents various ways to carry out multiple regressions. One easy way is to use the lm() function of the GLM package. In this post I will present how to use the lm() and run OLS on the following model

Unfortunately, linreg() is deprecated and no longer exists in Julia v1.0. In case you are using Julia v1.0 or above, check out this post. In case you use a version of Julia that is older than 1.0, i.e 0.7, 0.6, etc., the following post will show you how to run a linear regression in Julia.

In a former blog post (see here) I described how to read an Excel file into Julia. In this post I will focus on how to import an Excel file directly from the Web. This feature might be especially useful for recurring routines that rely on the most up-to-date data. Continue reading How to Read an Excel File dircetly form the Web in Julia Language?
