Constructor Details

EmpiricalDistributionForExpression

public EmpiricalDistributionForExpression(GeneralizedSemPm semPm,
 Node error,
 Context context)

Constructor for EmpiricalDistributionForExpression.

Parameters:

semPm - a GeneralizedSemPm object

error - a Node object

context - a Context object

Method Details

getDist

public org.apache.commons.math3.distribution.RealDistribution getDist()

Generates an empirical cumulative distribution function (CDF) based on the evaluation of an expression over a repetitive sampling process. The method retrieves an expression associated with a specified error node, evaluates the expression in a specified context over 5000 iterations, and collects the results. These collected values are then used to construct and return an empirical CDF.

Returns:

a RealDistribution object representing the empirical cumulative distribution function (CDF) generated based on the evaluated sample values.
