Distribution poisson(mean) 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 poisson().
- Description
- Generates a sample of the truncated Poisson distribution.
- Parameters
-
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". mean double The mean value for the distribution = rate of event occurrence. 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 int The generated sample.
