These approximations tend to be much simpler than the exact formulas and, as a result, provide a basis for insight and understanding that often would be difficult to obtain otherwise. sample – a sample is a subset of the population. For example, "largest * in the world".

This means that Z ∼ AN(0,1), when n is large. IIn this situation, for all practical reasons, the t-statistic behaves identically to the z-statistic. High-dimensional testing. Estimating equations and maximum likelihood. Note: Technically speaking we are always using the t-distribution when the population variance σ2 is unknown.

These notes are designed to accompany STAT 553, a graduate-level course in large-sample theory at Penn State intended for students who may not have had any exposure to measure-theoretic probability. The theory of large deviations deals with rates at which probabilities of certain events decay as a natural parameter in the problem varies.
