Title: basic mean and standard deviation
Post by SamW on Feb 11^th, 2011 at 10:53am

Are there macros for mean and standard deviation on a vector of data points? If so, can you point me to it?

Thanks,
Sam

Hi Sam,

Look at TemplateBatchFiles/Utility/DescriptiveStatistics.bf
There is a function there (GatherDescriptiveStats) which returns all kinds of summary and descriptive stats.

For example, try:

Code (]

RequireVersion("2.0020110101")
someValues = {100,1}["Random(0,1)"):

;
LoadFunctionLibrary ("DescriptiveStatistics");

fprintf (stdout, GatherDescriptiveStats (someValues));
