Chapter 2: Statistics LET Subcommands


For a number of Dataplot statistical tests, there are corresponding Statistics LET Subcommands for generating the value of the test, the p-value of the test statistic, the CDF of the test statistic, and so on. These commands are typically documented with the statistical test rather than here. However, they are listed in "LIST OF SUPPORTED STATISTICS" page.
