The function accepts the following arguments: v: [in] double degrees of freedom. double stdlib_base_dists_t_skewness( const double v ); Examples #include "stdlib/stats/base/dists/t/skewness.h" #include <stdlib.h> #include <stdio.h> static double random_uniform( const double min, const...
Note: There isn’t an Excel function to find Pearson’s coefficient of skewness. In the descriptive statistics area of the data analysis tool, skewness of data is calculated by using the third power of deviations around the mean. This is different from Pearson’s coefficient of skewness, which...
