CStats:StatsStr

The StatsStr method computes the mean, standard deviation, and other basic statistics for numeric data and returns them in a keyed table with each statistic being the key name.

Syntax

tbl = CStats:StatsStr( CImage, CRect )

tbl = CStats:StatsStr( CImage )

tbl = CStats:StatsStr( CArray )

tbl = CStats:StatsStr( table )

    CRect is a bounding rectangle for the CImage object.

    CArray is a CArray object.

    tbl is a 1-dimensional table containing keyed values.

    The returned value tbl is a keyed table containing 8 named members:

      nMean is the mean value.

      nMedian is the median value.

      nSdev is the standard deviation.

      nMin is the minimum value.

      nMax is the maximum value.

      nSkewness is the statistical skewness.

      nKurtosis is the statistical kurtosis.

      nCount is the number of values in the sample.

    On success, tbl is returned.

    On failure, returns nil.

Example

Suppose a CImage I exists. The following script returns the mean and standard deviation of 600 pixels in the corner of the image:
