Field statistics

 

fldstat Macro command for computing statistics for fields
-d <srcdata> source data frame
-dout <trgdata> target data for statistics in classes
[-min] find minimum values
[-max] find maximum values
[-sum] compute sum values
[-avg] compute average values
[-var] compute variances
[-dev] compute standard deviations
[-md <value>] missing value to be skipped

This is a macro command, which includes the commands listed in the following section. Each operation stores results in one field meaning that, for instance, all minimum values from the data fields will be stored in one field. New fields, which are created into <trgdata>, are named with the name of the operation performed (min, max, sum, avg, ...).
