' Function by Patrick Matthews
' This Access UDF calculates various stats for the values passed into the ParamArray. It
' was originally designed for passing several values from a particular row set for
' evaluation; since the values come from the same row, the usual aggregate functions would
' not be appropriate.
' The Stat variable (NOT case sensitive) determines what statistic is calculated:
' "min", "max": minimum or maximum
' "sum", "avg": sum or average, excluding dates or strings
' "var", "stdev": sample variance or standard deviation (excluding dates or strings)
' "varp", "stdevp": sample variance or standard deviation (excluding dates or strings)
' You may pass any value in the ParamArray. Strings, nulls, and dates are ignored for the
' sum, avg, stdev, stdevp, var, and varp calculations. (Thus, you could use this function to
' add several columns together without wrapping each column with Nz() to handle nulls...)
