vcovAdj (Package: pbkrtest) :

Kenward and Roger (1997) describbe an improved small sample approximation to the covariance matrix estimate of the fixed parameters in a linear mixed model.

● Data Source: CranContrib
● Keywords: function
● Alias: vcovAdj, vcovAdj.lmerMod, vcovAdj0, vcovAdj2, vcovAdj_internal

PBrefdist (Package: pbkrtest) :

Calculate reference distribution of likelihood ratio statistic in mixed effects models using parametric bootstrap

● Data Source: CranContrib
● Keywords: models, utilities
● Alias: PBrefdist, PBrefdist.lm, PBrefdist.mer, PBrefdist.merMod

PBmodcomp (Package: pbkrtest) :

Model comparison of nested models using parametric bootstrap methods. Implemented for some commonly applied model types.

KenwardRoger (Package: pbkrtest) : Ftest and degrees of freedom based on Kenward-Roger approximation

An approximate F-test based on the Kenward-Roger approach.

● Data Source: CranContrib
● Keywords: function
● Alias: KRmodcomp, KRmodcomp.lmerMod, KRmodcomp_internal

model2restrictionMatrix (Package: pbkrtest) :

Testing a small model under a large model corresponds imposing restrictions on the model matrix of the larger model and these restrictions come in the form of a restriction matrix. These functions converts a model to a restriction matrix and vice versa.

● Data Source: CranContrib
● Keywords: models, utilities
● Alias: model2restrictionMatrix, model2restrictionMatrix.lm, model2restrictionMatrix.mer, model2restrictionMatrix.merMod, restrictionMatrix2model, restrictionMatrix2model.lm, restrictionMatrix2model.mer, restrictionMatrix2model.merMod

pbkrtest-internal (Package: pbkrtest) : Internal functions in the pbkrtest package

Internal functions called by other functions.

● Data Source: CranContrib
● Keywords: internal
● Alias: plot.PBmodcomp, print.PBmodcomp, print.summaryPB, summary.PBmodcomp
● 0 images

getKR (Package: pbkrtest) :

Extract (or "get") components from a KRmodcomp object, which is the result of the KRmodcomp function.

● Data Source: CranContrib
● Keywords: models
● Alias: getKR

get_Lb_ddf (Package: pbkrtest) :

Get adjusted denomintor degress freedom for testing Lb=0 in a linear mixed model where L is a restriction matrix.

● Data Source: CranContrib
● Keywords: utilities
● Alias: Lb_ddf, get_Lb_ddf, get_Lb_ddf.lmerMod
