RiskGeomet
|
Description |
RiskGeomet(p) specifies a geometric distribution with parameter p. This distribution is usually used to model the number of trials before the first “success” in a sequence of independent, identical trials with probability p of success on each trial. For example, it could be used in a maintenance model to represent the number of months before a car breaks down. However, because the distribution requires a constant probability of breakdown per trial, other models, where the probability of breakdown increases with age, might be more realistic.

Examples |
RiskGeomet(0.25) returns a geometric distribution with a 25% probability of success on each trial. RiskGeomet(A18) returns a geometric distribution with a probability of success on each trial taken from cell A18.
