semEff 0.3.0

New features:

• Support for mixed models of class “lmerModLmerTest”
• New function ‘glt’, for calculating ‘generalised’ link transformations for non-gaussian variables

Other changes:

• Transfer of some functionality from ‘getY’ to ‘glt’
• Minor changes to arguments in ‘bootEff’ and ‘getY’
• Added ability in ‘stdCoeff’ to use variables not present in the model design matrix (e.g. a ‘missing’ main effect for an interaction)
• Added ability to pass a boot object (from ‘bootEff’) to the ‘effects’ argument of ‘predEff’
• Added a ‘refit.x’ argument to ‘stdCoeff’, allowing control over whether to refit the model with centred predictors (for correct VIFs)
• Various updates to documentation

Bugs fixed:

• ‘xNam’ did not generate correct term names for categorical variables with contrast types other than ‘contr.treatment’
• ‘stdCoeff’ did not correctly adjust for multicollinearity for a model containing categorical variables when centring was specified (‘cen.x = TRUE’)
• ‘getY’ failed to generate an estimated working response when a variable with missing values (NAs) was supplied (this functionality now in ‘glt’)
• ‘predEff’ failed for models with categorical variables (did not access dummy variables in model matrix)

semEff 0.2.1

Bugs fixed:

• Function ‘semEff’ does not output effects properly

semEff 0.2.0

New features:

• Added support for generalised least squares models (class “gls”)
• Added support for beta regression models (class “betareg”)

Bugs fixed:

• Function ‘xNam’ does not generate correct term names for interactions involving multi-coefficient terms (e.g. factors)
• Function ‘xNam’ does not generate correct term names for factors when the model intercept is suppressed
• Function ‘R2’ with argument ‘pred = TRUE’ throws an error for models where any weights = 0

semEff 0.1.0

New package ‘semEff’, allowing the automatic calculation of effects for ‘piecewise’ structural equation models.
