AVARIANCE() Short: ------ AVARIANCE() Determines the variance of an array with condition Returns: -------- <nVariance> => Array variance Syntax: ------- AVARIANCE(aTarget,[bCondition]) Description: ------------ <aTarget> is the target array. Normally an array of numeric values. [bCondition] is an optional codeblock used to select a subset of the array. This could be used to filter out 0's or non-numeric elements. The block must accept an array element as a parameter, and return true or false <expL> to determine if this element is part of the desired subset. Examples: --------- v := AVARIANCE(aSales) v := AVARIANCE(aSales,{|e|valtype(e)=="N".and.e<>0}) Source: ------- S_ASTATS.PRG
