17 Statistics

Origin provides a number of statistical routines suitable for general statistical analyses, including descriptive statistics, one-sample and two-sample hypothesis tests, and one-way and two-way analysis of variance (ANOVA). In addition, several statistical chart types are offered, including histograms and box charts.

Additional, advanced statistical analysis tools, such as repeated measures ANOVA, relative operating characteristic curves (ROC curves), power and sample size computation, and nonparametric tests are available in OriginPro.

Many of Origin's statistical analyses rely on functions from the Numerical Algorithms Group (NAG) library. More details of the code and analysis for these functions can be found in the NAG documentation.

This Manual/Help file chapter covers basic information on Origin's statistical analysis tools. For more detailed information on a statistical test, please refer to the X-Function Help file (Help: X-Functions). Topics in the X-Function Help file are organized by application and are named with the X-Function name.

X-Function-specific help can be opened by typing the following at the command prompt in the Command Window:

help X-FunctionName

An abbreviated "quick help" showing command line usage, can be accessed for any X-Function by typing the following at the command prompt:

X-FunctionName -h
