KDATA_PMFSTDDEV(3) Library Functions Manual KDATA_PMFSTDDEV(3) NAME kdata_pmfstddev -- compute probability mass function standard deviation of data LIBRARY libkplot SYNOPSIS #include <cairo.h> #include <kplot.h> double kdata_pmfstddev(const struct kdata *data); DESCRIPTION The kdata_pmfstddev function compute the standard deviation (i.e., the square root of kdata_pmfvar(3)) of its data as if it were a probability mass function. RETURN VALUES If the data source has zero entries or the sum of the y values is 0.0, kdata_pmfstddev returns 0.0. Otherwise, it returns the standard deviation. SEE ALSO kdata_pmfmean(3), kdata_pmfvar(3), kplot(3) FreeBSD ports 15.quarterly January 29, 2015 KDATA_PMFSTDDEV(3)
