Description Details Author(s) References

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, pgls, sarlm, lme, glmmPQL, lmerMod,
merModLmerTest, glmerMod
```

Package: | piecewiseSEM |

Type: | Package |

Version: | 2.0.2 |

Date: | 2018-07-24 |

Depends: | R (>= 3.5.0), nlme, pbkrtest |

Suggests: | MASS, lme4 |

The primary
functions in the package are `psem`

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

can be used on an object of
class `psem`

to provide various summary statistics for evaluation and
interpretation.
