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
