mo()
with
numeric predictors, which only allow to predict for values that are actually
present in the data.Fixed issue with adding raw data points for plots from logistic regression models, when the response variable was no factor with numeric levels.
Fixed issues with CRAN checks.
orm
(package rms)Prediction intervals (where possible, or when type = "random"
), are now
always based on sigma^2 (i.e. insight::get_sigma(model)^2
). This is in
line with interval = "prediction"
for lm, or for predictions based on
simulations (when type = "simulate"
).
print()
now uses the name of the focal variable as column name (instead)
of "x"
).
collapse_by_group()
, to generate a data frame where the response value of
the raw data is averaged over the levels of a (random effect) grouping factor.A new vignette was added related to the definition and meaning of "marginal effects" and "adjusted predictions". To be more strict and to avoid confusion with the term "marginal effect", which meaning may vary across fields, either "marginal effects" was replaced by "adjusted predictions", or "adjusted predictions" was added as term throughout the package's documentation and vignettes.
Allow confidence intervals when predictions are conditioned on random effect
groups (i.e. when type = "random"
and terms
includes a random effect
group factor).
Predicted response values based on simulate()
(i.e. when
type = "simulate"
) is now possible for more model classes
(see ?ggpredict
).
ggpredict()
now computes confidence intervals for some edge cases where
it previously failed (e.g. some models that do not compute standard errors
for predictions, and where a factor was included in the model and not the
focal term).
plot()
gains a collapse.group
argument, which - in conjunction with
add.data
- averages ("collapses") the raw data by the levels of the
group factors (random effects).
data_grid()
was added as more common alias for new_data()
.
ggpredict()
and plot()
for survival-models now always start with time = 1.
Fixed issue in print()
for survival-models.
Fixed issue with type = "simulate"
for glmmTMB
models.
Fixed issue with gamlss
models that had random()
function in the
model formula.
Fixed issue with incorrect back-transformation of predictions for
geeglm
models.
residuals.type
argument in plot()
is deprecated. Always using "working"
residuals.pretty_range()
and values_at()
can now also be used as function factories.
plot()
gains a limit.range
argument, to limit the range of the prediction bands to the range of the data.
Fixed issue with unnecessary back-transformation of log-transformed offset-terms from glmmTMB models.
Fixed issues with plotting raw data when predictor on x-axis was a character vector.
Fixed issues from CRAN checks.
interval
to ggemmeans()
, to either compute confidence or prediction intervals.averaging
(package MuMIn)pool_predictions()
, to pool multiple ggeffects
objects. This can be used when predicted values or estimated marginal means are calculated for models fit to multiple imputed datasets.residualize_over_grid()
is now exported.log1p()
and log(mu + x)
.type = "random"
or "zi_random"

.ggemmeans()

.terms = "predictor [exp]"

(package mlogit)plot()
now can also create partial residuals plots. There, arguments residuals
, residuals.type
and residuals.line
were added to add partial residuals, the type of residuals and a possible loess-fit regression line for the residual data.glm
since some time. Should be fixed now.ggpredict()
and rlmerMods
models when using factors as adjusted terms.mclogit
(package mclogit)ggeffect()
.ggpredict()

, to predict the zero-inflation probability (for models from pscl, glmmTMB and GLMMadaptive).add.data = TRUE
in plot()
, the raw data points are also transformed accordingly.plot()
with add.data = TRUE
first adds the layer with raw data, then the points / lines for the marginal effects, so raw data points to not overlay the predicted values.terms

was not specified.type

.ggpredict()
