Detailed Description

Represents multicomponent continues distribution.

For example let the user to create a distribution consisting of mixed Gaussian components or a mixed Normal/Exponential distribution.

Here is an example of it's usage:

set ndist = ##class(DeepSee.extensions.stat.NormalDistribution).create(m, (sigma * sigma)) set edist = ##class(DeepSee.extensions.stat.ExpDistribution).create(lambda) set mdist = ##class(DeepSee.extensions.stat.MixedDistribution).New() set sc = mdist.AddComponent(ndist, w) Quit:$$$ISERR(sc) set sc = mdist.AddComponent(edist, (1-w)) Quit:$$$ISERR(sc) set sc = mdist.balance() Quit:$$$ISERR(sc) w "Mean = "_mdist.Mean w "; Var = "_mdist.Variance w "; Entropy = "_mdist.Entropy, !

Member Function Documentation

◆ AddComponent()

_.Library.Status AddComponent	(	_.DeepSee.extensions.stat.AbstractContinuousDistribution	p,
		_.Library.Double	weight
	)

Add a component p to the distribution with the given weight.

After all components

are added application must call <METHOD>balance</METHOD>

◆ cdf()

_.Library.Double cdf	(	_.Library.Double	x1,
		_.Library.Double	x2
	)

An interface method for cumulative distribution function (CDF).

Optionally provides a cumulative probability

of a value being between two values x1 and x2.

If called with 1 argument(x1) or if the value of second argument is empty string then returns CDF value for x1. If called with two arguments, x1 and x2 then returns a probability of a value being between x1 and x2.

Reimplemented from AbstractContinuousDistribution.
