Calculates total covariance matrix

1	totalCov(variables, div_by_n = FALSE)

`variables`	matrix or data frame with explanatory variables (No missing values are allowed)
`div_by_n`	logical indicating division by number of observations

When div_by_n=TRUE the covariance matrices are divided by n (number of observations), otherwise they are divided by n-1
