Distribution gamma(alpha, 1, 0) is stretched by stretch coefficient, then shifted to the right by shift. After that it is truncated to fit in [min, max] interval. Truncation is performed by discarding every sample outside this interval and taking subsequent try.
For more details, see gamma().
- Description
- Generates a sample of the truncated Gamma distribution.
- Parameters
-
Name Type of value Description min double The minimum value that this function will return. The distribution is truncated to return values above this. If the sample (stretched and shifted) is below this value, it will be discarded and another sample will be drawn. Use -infinity for “No limit”. max double The maximum value that this function will return. The distribution is truncated to return values below this. If the sample (stretched and shifted) is bigger than this value, it will be discarded and another sample will be drawn. Use infinity for “No limit”. alpha double The shape parameter > 0. Also known as order. If less than 1, then 1 will be used. shift double The shift parameter that indicates how much the (stretched) distribution will be shifted to the right. stretch double The stretch parameter that indicates how much the distribution will be stretched. - Result
-
Type Description double The generated sample.
