When you want to predict multiple target values for the same set of predictor variables, you need to use multivariate multiple linear regression. Multivariate linear regression takes an array of a set of predictors and an associated list of outcomes for each of this predictor set of values.
In this example, we will use Accord.NET to find the relationships between several data:
Get Accord Statistics via NuGet by giving the following command in PM console:
PM> Install-Package Accord.Statistics -Version 2.15.0
Once you install this package, the following code finds coefficients of the multivariate linear regression for sample data:
