GetThresholdValuesKernel: Calculate item threshold values for kernel parameterization

Description

Calculates the item threshold values for a kernel parameterization of a DCM model using lambdas

Usage

GetThresholdValuesKernel(lambda.equations, estimates0, threshold.labels)

Arguments

lambda.equations
an nclasses by nitems character matrix with tau values represented as a function of lambda values
estimates0
a numeric vector of parameter estimates in the form of lambdas and gammas
threshold.labels
an nclasses by nitems character matrix with appropriate threshold labels.

Value

a list of a numeric vector of item threshold values and an nclasses by nitems numeric matrix of item threshold values
