Minor update: Use new Stan array syntax thanks to Andrew Johnson.

Minor fix: Let rstantools generate Makevars

Minor housekeeping:

- Updated compiler flags thanks to @jgabry
- Updated contact info

Updated compiler flags for new version of RStan thanks to Andrew Johnson.

Fix package for staged installation

- Fix NOTE about methods package

- Update to C++14, thanks to Ben Goodrich.

- Removed
`tab2doc()`

, package no longer needs archived ReporteRs package.

- Deprecate
`tab2doc()`

because required package ReporteRs is archived.

- Fix (harmless) constructor error message

- Minor cleaning of Stan code
- Fix typos in documentation

- Change the label ‘%me’ to ‘pme’ (for proportion mediated effect) in output of mlm_path_plot(…, text = TRUE).

- Add options to
`mlm_spaghetti_plot()`

to allow jittering and adjusting size of the error bars.

`mlm_spaghetti_plot()`

now has argument`mx`

which can be set to`mx = "data"`

to plot the spaghetti plot of the M - Y relationship (b path) such that the X values are from data, and not fitted values from the X - M model (a path). The argument defaults to`mx = "fitted"`

, such that the X axis values of the M - Y spaghetti plot are fitted values.

- New function
`mlm_spaghetti_plot()`

for visualizing model-fitted values for paths a (X->M regression) and b (M->Y regression)

- Default priors are now \(Normal(0, 1000)\) for regression coefficients, and \(Cauchy(0, 50)\) for group-level SDs
`mlm_summary()`

now gives only population level parameters by default, and group-level parameters when`pars = "random"`

- Renamed the mediated effect parameter to
*me*to distinguish it from the product of*a*and*b*(similarly for group-level*u_me*) `mlm_path_plot()`

now draws a template if no model is entered (i.e.`template`

argument is deprecated)`mlm_path_plot()`

now by default also shows SDs of group-level effects. This behavior can be turned off by specifying`random = FALSE`

- The fitted model object doesn’t contain the whole covariance matrix anymore, but now contains the group-level intercepts
- New example data set included in package:
`MEC2010`

- Posterior standard deviation is now referred to as SE in
`mlm_summary()`

Removed sigma_y from being modeled when binary_y = TRUE.

Removed posterior probabilities from default outputs.

Added type = “violin” as option for plotting coefficients with mlm_pars_plot().

Users may now change each individual regression parameter’s prior, instead of classes of priors.

Users may now change the shape parameter of the LKJ prior.

Coefficient plots now reorder parameter estimates, if user has requested varying effects.

Path plot now by default does not scale the edges.

bmlm now uses pre-compiled C++ code for the Stan models, which
eliminates the need to compile a model each time `mlm()`

is
run. This significantly speeds up model estimation.

The Stan code used by `mlm()`

is now built from separate
chunks, allowing more flexible and robust model development.

Initial release to CRAN.
