Various

Various functions not intended for user.

Description

Functions used in the process of estimating parameters and standard errors of ordered generalized linear models.

Usage

updateComponents(Env,Parameters)

oglmx.maxlik(inputenv,start)

loglikelihood.oglmx(Env)

score_oglmx(Env)

hessian_oglmx(Env)

calcBHHHmatrix(Env)

mergeformulas(formula1,formula2)

calcstartvalues(whichparameter,gfunc,threshvec)

getThresholds(outcomematrix,thresholdvector)

Probability(eta_1,eta_0,link)

Arguments

`Env, inputenv`	environment, typically constructed by the `oglmx.fit` function, that contains all relevant information for the optimisation process.
`Parameters, start`	numeric vector of length equal to the number of estimated parameters.
`formula1, formula2`	items of class `formula`.
`whichparameter`	logical
`gfunc`	expression, function used to model the variance
`threshvec, thresholdvector`	numeric vectors of threshold values
`outcomematrix`	numeric matrix with binary variables indicating the outcome for each observation
`eta_1,eta_0`	input values for the link function
`link`	string value indicating which link function is to be used
