v.normal computes tests of normality on vector points.
The tests that v.normal performs are indexed below. The tests that are performed are specified by giving an index, ranges of indices, or multiple thereof.
Compute the sample skewness and kurtosis, Geary’s
a-statistic and an approximate normal transformation, extreme normal
deviates, and Royston’s W for the random vector points:
g.region raster=elevation -p v.random random n=200 v.db.addtable random column="elev double precision" v.what.rast random rast=elevation column=elev v.normal random tests=1-3,14 column=elev
