In oglmx: Estimation of Ordered Generalized Linear Models

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
