0.8.8: Updates
0.8.7: Updates
- The package "aldvmm" now uses analytical gradients instead of numerical approximations during optimization and in methods used for estimators from the "sandwich" package.
- New methods for generic functions stats::formula(), stats::residuals() and stats::update(). Objects of class "aldvmm" can now be supplied to sandwich::sandwich(), sandwich::vcovCL(), sandwich::vcovPL(), sandwich::vcovHAC() and sandwich::vcovBS(). sandwich::vcovBS() allows re-estimating the covariance matrix using bootstrapping with and without clustering.
- Objects of class "aldvmm" now include predicted probabilities of component membership for all observations in the estimation data.
- New html vignette.
0.8.6: Updates
- Default optimzation method was changed to "BFGS".
- New methods for generic functions print(), summary(), stats::predict(), stats::coef(), stats::nobs(), stats::vcov(), stats::model.matrix() and sandwich::estfun() are available. Objects of class "aldvmm" can now be supplied to sandwich::sandwich(), sandwich::vcovCL(), lmtest::coeftest(), lmtest::coefci() and other functions.
- New workflow using the function Formula::formula() to handle models with two right-hand sides.
- Objects of class "aldvmm" include new elements:
- n: The number of complete observations.
- df.null: Degrees of freedom of null model.
- df.residual: Degrees of freedom of fitted model.
- iter: The number of iterations during optimization.
- convergence: An indicator of successful completion of optimization.
- call: A character value of the model call.
- terms: A list of terms objects for the models.
- data: A data frame of the estimation data.
- contrasts: A nested list of character values of contrasts.
- na.action: An object indicating the na.action used in stats::model.frame()
0.8.5: Updates
- Update in validate_aldvmm(): Checking for class type of model formula using base::inherits() instead of if(class(obj) == "formula").
- Update in vignette: Include figures as .eps files to avoid loading ggplot objects from previous versions of ggplot2.
