procedure NormalStat(Mu: Double; sigma: Double; out AMean: Double; out AVariance: Double; out ASkewness: Double; out AKurtosis: Double);
Normal distribution moments (mean, variance, skewness, excess kurtosis).
| # | Name | Description |
|---|---|---|
| 1 | AMean | Returns the distribution mean, = Mu. |
| 2 | AVariance | Returns the distribution variance, = sigma^2. |
| 3 | ASkewness | Returns the distribution skewness, = 0. |
| 4 | AKurtosis | Returns the EXCESS kurtosis, = 0. |
| 5 | Mu | Distribution location parameter (mean), any real value. |
| 6 | sigma | Distribution scale parameter (standard deviation), real value > 0. |
Result: stored in self (calling object)
Remarks:
Returns the moments of the normal distribution: mean mu, variance sigma^2, skewness 0 and excess kurtosis 0. If sigma <= 0 all four outputs are NAN.
