modify examples, for CRAN compliance
reduced size of stored fits for examples, for CRAN compliance
more consistent term names in brmsfit, rstanreg tidiers
improved tidy.MCMCglmm
all methods return tibbles (tbl_df) rather than data
frames
the value of the group variable for fixed-effect
parameters has changed from "fixed" to NA
brmsfit and rstanarm tidiers are more
consistent with other tidiers (e.g. conf.level rather than
prob)
Sorted out some of the confusion over random effect naming: "ran_vals" extracts conditional modes/BLUPs/varying parameters (deviations from population-level estimates), while "ran_coefs" extracts group-level estimates
improved nlme tidiers
improved glmmTMB tidiers (can handle some
zero-inflation parameters)
lme4 tidiers now optionally take a pre-computed
profile argument when using conf.method="profile"
The default behaviour of most mixed-model tidiers has changed/will gradually be changed to the following (description modified from TJ Mahr at https://github.com/tidyverse/broom/issues/96):
Random effect variances and covariances can now be extracted.
effects = "ran_pars" returns the standard deviations/correlations
of random effects (if scales="sdcor" [default])
or their variances
and covariances (if scales = "varcov")
Random effects estimates are now extracted with
effects = "ran_coefs" for the group-level
estimates (previously these effects were
extracted with tidy(model, "random")) or
effects = "ran_vals" for the conditional modes
(deviations of the group-level parameters from the
population-level estimates)
effects can take a vector of values (those listed
above, plus "fixed" for fixed effects). The default value
is effects = c("ran_pars", "fixed") which extracts random
effect variances/covariances and fixed effect estimates.
term names for random-effect parameters no longer
contain a (redundant) group specifier (at least for lme4
models); use something like
tidyr::unite(term,term,group,sep=".")
to collapse the two columns
