pcvrss-class

pcvrss

Models specified by growthSS or mvSS are represented by a <code>pcvrss</code> object,
which contains the model type, formulas, starting values or priors, the data for the model
to use, and the model backend to use.

Analyse common types of plant phenotyping data, provide a simplified interface
to longitudinal growth modeling and select Bayesian statistics,
and streamline use of 'PlantCV' output.
Several Bayesian methods and reporting guidelines for Bayesian methods are described in
Kruschke (2018) <doi:10.1177/2515245918771304>,
Kruschke (2013) <doi:10.1037/a0029146>, and Kruschke (2021) <doi:10.1038/s41562-021-01177-7>.
