Distribution beta(p, q, 0, 1) 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 the subsequent try.
For more details see beta().
Generates a sample of truncated Beta distribution.
Name |
Type | 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". |
p |
double |
The lower shape parameter > 0. Also known as alpha parameter. |
q |
double |
The upper shape parameter > 0. Also known as beta parameter. |
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. |
