PROC DISCRETE-A Procedure for Fitting Discrete Probability Distributions
... Individual distributions may be fitted by requesting the following options. If no distributions are requested, all eight distributions will be fitted. POlS - Poisson distribution POSB - positive binomial distribution NEGB - negative binomial distribution THOM - Thomas double poisson distribution NEY ...

... The median of a density curve is the equal-areas point, the point that divides the area under the curve in half. The mean of a density curve is the balance point, at which the curve would balance if made of solid material. The median and the mean are the same for a symmetric density curve. They both ...

Discrete Probability Distributions
... real-life situations are made by assigning probabilities to all possible outcomes pertaining to the situation and then evaluating the results. For example, a saleswomen can compute the probability that she will make 0,1,2 or 3 or more sales in a single day. An insurance company might be able to assi ...

... An F-test is a simple calculation to compare the precision of two sets of measurement. The sets do not have to be obtained from the identical sample, so long as both samples are sufficiently similar that any indeterminate errors can be considered the same. An Ftest can provide insights into two main ...
