An international team of researchers, led by UMass Amherst biostatistician Leontine Alkema and her former Ph.D. student Fengqing Chao, developed a new estimation method for assessing natural ...

Freidlin and Korn 9 critically review some of the alternative methods. Their conclusion is that these methods can be useful as secondary analyses, but they are not ready to be used in primary analysis ...

An observation is to be classified into one of two multivariate normal distributions with equal covariance matrices. When the parameters are unknown, four methods of estimating the likelihood ratio, ...

Statistical graphics are a fundamental, yet often overlooked, set of components in the repertoire of data analytic tools. Graphs are quick and efficient, yet simple instruments for preliminary ...

Each estimation method is based on finding parameter estimates that minimize a badness-of-fit function that measures the difference between the observed sample covariance matrix and the predicted ...
