skewness¶
Purpose¶
Compute the sample skewness.
Format¶
-
g =
skewness
(x[, bias])¶ - Parameters:
x (Matrix) – Nxk, sample data.
bias (Scalar) – Optional argument. Indicator for bias correction. If anything other than 0, bias correction is used. Default = 0.
- Returns:
g (Scalar) – Sample skewness.
Examples¶
Example One: Vector input¶
// Generate random vector of residuals
rndseed 929212;
resid = rndn(150, 1);
// Compute sample skewness
g = skewness(resid);
The code above results in the following:
g = 0.3049
Example Two: Matrix input¶
// Generate random vector of residuals
rndseed 929212;
resid = rndn(150, 2);
// Compute sample skewness
g = skewness(resid);
The code above results in the following:
g = 0.26494746 -0.14941577
