## Correlation Plot

Let’s start visualizing correlation values in a plot.Open your RStudio and begin typing in !!! Let's import the library corrplot for correlation matrix visualization library(corrplot) Let's store the dataset mtcars into dataframe named DataFrame DataFrame <- mtcars Let's find the correlation matrix of this data set corrMatrix <- cor(DataFrame) Let'c visualize the correlation matrix.This plot […]

## Finding patterns in Predictor Variables

Finding correlated variables is very important in order to remove multicollinearity in multiple regression models.Once you know the correlated variables you can choose few from them or may be just one from them.It depends on correlation value and other factors.Let’s begin to visualize the correlation in variables in a nice plot.Open your RStudio and begin […]
