Multivariate normal distribution

We often assume that our data is normally distributed. This is often a good approximation in practice of the real but unknown distribution of your data. We discuss in this lecture the multivariate normal distribution: the density function, the Mahalanobis distance, the contour of the density plot.

Very good approach about it!! Do you have some problems or example where apply bivariate analysis in real life?
