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.

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.
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?
This article shortly describes how to read an Excel file into Julia. Generally, one can use different libraries to read Excel files, including XLSXReader , ExcelReaders or Taro. In this tutorial I will focus on Taro as it created the fewest problems and provides – at least in my eyes – an easy to understand syntax.

Julia has been around since a couple of years now and continues to attract new users. Julia Language uses concepts from well established programming languages in order to create an easy-to-use high performance software.
The official website describes Julia as
