Piecewise structural equation modeling

Fitting and evaluation of piecewise structural equation models, complete
with goodness-of-fit tests, estimates of (standardized) path coefficients,
and evaluation of individual model fits (e.g., through R-squared values).
Compared with traditional variance-covariance based SEM, piecewise SEM
allows for fitting of models to different distributions through GLM and/or
hierarchical/nested random structures through (G)LMER. Supported model
classes include: ```
lm, glm, gls, Sarlm, lme, glmmPQL, lmerMod, merModLmerTest,
glmerMod, glmmTMB, gam
```

The primary functions in the package are `psem`

which unites structural equations in a single model, and `summary.psem`

can
be used on an object of class `psem`

to provide various summary statistics for
evaluation and interpretation.
