new features
- Add support for generalized additive mixed models
(GAMMs). Smoothing terms can be specified using
thes
andt2
functions in the model formula. - Introduce
as.data.frame
andas.matrix
methods forbrmsfit
objects.
other changes
- The
gaussian("log")
family no longer implies
a log-normal distribution, but a normal distribution with
log-link to match the behavior ofglm
.
The log-normal distribution can now be specified via
familylognormal
. - Update syntax of
Stan
models to match the
recommended syntax ofStan
2.10.
bug fixes
- The
ngrps
method should now always
return the correct result for non-linear models. - Fix problems in
marginal_effects
for
models using the reserved variableintercept
thanks to Frederik Aust. - Fix a bug in the
print
method of
brmshypothesis
objects that could lead to
duplicated and thus invalid row names. - Residual standard deviation parameters of
multivariate models are again correctly displayed
in the output of thesummary
method. - Fix problems when using variational Bayes
algorithms withbrms
while having
rstan
>= 2.10.0 installed thanks to the
Github user cwerner87.
