An application of Bayes Theorem that performs the same calculations for the situation where the several probabilities are constructed as indices of subjective confidence.

This page will generate a graphic and numerical display of the properties of a binomial sampling distribution, for any values of p and q, and for values of n between 1 and 40, inclusive.
Generate a graphic and numerical display of the properties of the Normal Distribution. For a unit normal distribution, with M=0 and SD=Œ±1, enter 0 and 1 at the prompt. For a distribution with M=100 and SD=Œ±15, enter 100 and 15. And so forth
Log-linear analysis is a version of chi-square analysis in which the relevant values are calculated by way of weighted natural logarithms. This page will calculate several values of G^2.
This page will perform an analysis of variance for the situation where there are three independent variables, A, B, and C, each with two levels. The user may enter data directly or copy and paste from a spreadsheet or other application.
This page will calculate the intercorrelations (r and r2) for up to five variables, designated as A, B, C, D, and E.
In this free online video program, "students will discover how to convert the standard normal and use the standard deviation; how to use a table of areas to compute relative frequencies; how to find any percentile; and how a computer creates a normal quartile plot to determine whether a distribution is normal. Vehicle emissions standards and medical studies of cholesterol provide real-life examples."
This page will perform basic multiple regression analysis for the case where there are several independent predictor variables, X1, X2, etc., and one dependent or criterion variable, Y. Requires import of data from a spreadsheet.
Probability is expectation founded upon partial knowledge. is a quote by George Boole (1815 - 1864) - the English logician and philosopher for whom Boolean logic is named. The quote is found in chapter 16 of his 1853 book "An Investigation of the Laws of Thought". The book can be found on-line through the Gutenberg project at www.gutenberg.org/etext/15114.
Song contains concepts and terms associated with linear regression. May be sung to the tune of "I Walk the Line" (Johnny Cash). Musical accompaniment realization and vocals are by Joshua Lintz from University of Texas at El Paso.
