WebThe matrix notation will allow the proof of two very helpful facts: * E b = β . This means that b is an unbiased estimate of β . This is a good thing, but there are circumstances in which biased estimates will work a little bit better. * Var b = () σ2 X′X −1. This identifies the variances and covariances of the Webtypical. Run any single-equation model (such as regress, probit, or logistic), and if you fetch the resulting matrices, you will ﬁnd that they have row and column names that use only opvarnames. Those who work with time-series data will ﬁnd matrices with row and column names of the form opvarname.
