mlts 2.0.0
mlts 2.0.0
New Features
- Deprecated
mlts_model_paths() and replaced with
mlts_paths().
- Inclusion of non-lagged (i.e., same time) directed effects via the
incl_t0_effects argument in mlts_model(). Note
that model formulas is not supported for these types of models at this
point.
- Inclusion of interaction effects on the dynamic within-level via the
incl_interaction_effects argument in
mlts_model(). Note that obtaining model formulas is not
supported for these types of models at this point.
- Multiple group analyses by specifying the
group
argument in mlts_model().
- Loosen the previous restriction of allowing only bivariate VAR
models with random innovation covariances. Models are still limited to
the incorporation of only one latent factor capturing the innovation
covariance, however, additional constructs can be added under the
assumption of independent innovations.
- Added option to include exogenous time-varying covariates (i.e.,
without latent-mean centering) using the
is_exogenous
argument in mlts_model()
- Add option to estimate models that assume censoring on the manifest
indicators using the
censor_left or
censor_right arguments in mlts_model().
- Provide option to introduce equality constraints on loading
parameters across levels in
mlts_model() using
equal_loads_levels = TRUE (i.e., fix between-level loading
parameter of an indicator to match the respective within-level loading
parameter).
- Obtain posterior predictive samples using
mlts_posterior_sample()
- Run posterior predictive checks
mlts_pp_check() (still
considered developmental).
- Option to limit the number of consecutive missing values in the a
subjects’ time series to avoid excessive numbers of
NAs
thereby improving model estimation times.
mlts_fit() now runs a small check to ensure that
observed grand-means of ts-variables match prior
distributions of the respective fixed effects. For multiple-indicator
models a simple message is printed if any mean values fall outside the
range of -10 to 10.
Changes
- Shortened column names in
summary output
- Reordered sections in
summary output
- Redundant constraint removed from re-transformed (i.e.,
exponentiated) individual variances in stan models
- When using
tinterval in mlts_fit() now
slices rows with NAs on all ts-variables prior
to the creation of the time grid
- True values of population parameters using
mlts_sim()
with default = TRUE changed slightly.
