Introduction and expected values
In this module, we cover the basics of the course as well as the prerequisites. We then cover the basics of expected values for multivariate vectors. We conclude with the moment properties of the ordinary least squares estimates.
The multivariate normal distribution
In this module, we build up the multivariate and singular normal distribution by starting with iid normals.
Distributional results
In this module, we build the basic distributional results that we see in multivariable regression.
Residuals
In this module we will revisit residuals and consider their distributional results. We also consider the so-called PRESS residuals and show how they can be calculated without re-fitting the model.
