Partial likelihood is a product of conditional likelihoods, used in certain situations for estimation and hypothesis testing. The basis of estimation in Cox’s proportional hazards model.

Partial Correlation is the correlation between a pair of variables after adjusting for the effect of a third.

Partial Autocorrelation is a measure of the correlation between the observations a particular number of time units apart in a time series, after controlling for the effects of observations at intermediate time points.

Parsimony Principle is the general principle that among competing models, all of which provide an adequate fit for a set of data, the one with the fewest parameters is to be preferred.

A test for assessing the quality of random number generators.

A bar chart with the bars ordered according to decreasing frequency enhanced by a line joining points above each bar giving the cumulative frequency.

Procedures for testing hypotheses about parameters in a population described by a specified distributional form, often, a normal distribution. Student’s t test is an example of such a method.

A hypothesis concerning the parameter(s) of a distribution. For example, the hypothesis that the mean of a population equals the mean of a second population, when the populations are each assumed to have a normal distribution.

Information processing involving a large number of units working contemporaneously in parallel with units, like the neurons of the brain, exciting or inhibiting one another.

A simple but powerful technique for obtaining a graphical display of multivariate data. In this plot, the variable axes are arranged horizontally, each parallel to the one above it. A line is then plotted for each observation by joining the appropriate variable values on these axes.
