StableDistribution
Stable probability distribution object
Description
StableDistribution
is an object consisting of parameters, a
model description, and sample data for a stable probability distribution.
The stable distribution uses the following parameters.
Parameter | Description | Support |
---|---|---|
alpha | First shape parameter | 0 < α ≤ 2 |
beta | Second shape parameter | -1 ≤ β ≤ 1 |
gam | Scale parameter | 0 < γ < ∞ |
delta | Location parameter | -∞ < δ < ∞ |
Creation
There are several ways to create a StableDistribution
probability
distribution object.
Create a distribution with specified parameter values using
makedist
.Fit a distribution to data using
fitdist
.Interactively fit a distribution to data using the Distribution Fitter app.
