Description

ALoguniformDistributionobject consists of parameters and a model description for a loguniform probability distribution, also referred to as a reciprocal distribution.

The loguniform distribution is a continuous distribution. Its density function is proportional to the reciprocal of the variable value within the support of the distribution (lower and upper limits).

The loguniform distribution uses the following parameters.

Parameter Description 金宝app
Lower Lower parameter 0 < Lower < Upper
Upper Upper parameter Lower < Upper < ∞

Creation

Distribution Parameters

Lower limit of the support of the loguniform distribution, specified as a scalar value.

Data Types:single|double

Upper limit of the support of the loguniform distribution, specified as a scalar value greater thanLower.
