1 | getSkewness(x, mean)
|
x |
is a study variable |
mean |
the arithmetic mean as a numeric value |
datasources |
a list of data connection parameters. |
Partial calculations of skew measure.
Considering x[i] for elements of x and x* for their mean, so m[r] = ∑{i}(x[i]-x*)^r is a partial sample moments of order r.
This function computes the 2nd and 3th partial sample moments.
A list with components:
m2 |
second sample moment. |
m3 |
third sample moment. |
