Probability Theory: Background and Bayes Theorem

The formalism of thought o ered by probability theory is one of the more useful portions of any beginning course in statistics in helping to promote ethical reasoning. As typically presented, we speak of an event represented by a capital letter, say A, and the probability of the event as some

data-analysis tasks, such as plotting data, computing descriptive statistics, and performing linear correlation analysis, data fitting, and Fourier analysis. Typically, the first step to any data analysis is to plot the data. After examining the plot, you can determine which portions of the data to include in the analysis.

Principal Component Analysis, Second Edition

terms ‘principal component analysis’ and ‘principal components analysis’ are widely used. I have always preferred the singular form as it is compati-ble with ‘factor analysis,’ ‘cluster analysis,’ ‘canonical correlation analysis’ and so on, but had no clear idea whether the singular or plural form was more frequently used.

Classification and Regression Trees

trees are used for prediction. In the last two decades, they have become popular as alternatives to regression, discriminant analysis, and other procedures based on algebraic models. Tree-fitting methods have become so popular that several commercial programs now compete for the atte ntion of market researchers and others looking for software.

Goodness of Fit in Logistic Regression

The x2 goodness-of-fit statistic assesses the magnitude of discrepancy between the sample and fitted covariance matrices, and it is the product of the sample size minus one and the minimum fitting function (denoted asT=(N- l)Fmn)- The T statistic (called %2 by other researchers) has an asymptotic (large sample) %2 distri-
