... 52. The mean length of a candy bar is 43 millimeters. There is concern that the settings of the machine cutting the bars have changed. Test the claim at the 0.02 level that there has been no change in the mean length. The alternate hypothesis is that there has been a change. Twelve bars (n = 12) wer ...

BASIC STATISTICS 1.1. Random Sample. The random variables X1
... 1.1. Random Sample. The random variables X1 , X2 , ..., Xn are called a random sample of size n from the population f(x) if X1 , X2 , ..., Xn are mutually independent random variables and the marginal probability density function of each Xi is the same function of f(x). Alternatively, X1 , X2 , ..., ...

... Determinantal point processes (DPPs) have recently proved to be a useful class of models in several areas of statistics, including spatial statistics, statistical learning and telecommunications networks. They are models for repulsive (or regular, or inhibitive) point processes, in the sense that ne ...

Chapter-5:Extreme Value Theory (EVT)
... The Fisher-Tippett theorem is the fundamental result in EVT and can be considered to have the same status in EVT as the central limit theorem has in the study of sums. The theorem describes the limiting behavior of appropriately normalized sample maxima. Suppose X 1 , X 2 ,K are a sequence of indepe ...
