stan_inits: Calculate Initial Values for Stan VM Model

Description

Internal function used to get rough starting values for a variability model in Stan. Uses inidivudal standard deviations, means, and linear regressions.

Usage

stan_inits(stan.data, design = c("V -> Y", "V -> M -> Y", "V", "X -> V", "X -> V -> Y", "X -> M -> V"), useU, ...)

Arguments

stan.data

A list containing the data to be passed to Stan

design

A character string indicating the type of model to be run. One of “V -> Y” for variability predicting an outcome, “V -> M -> Y” for mediation of variability on an outcome, “V” to take posterior samples of individual variability estimates alone.

useU

whether to include the random intercepts

...

Additional arguments (not currently used)

Value

A named list containing the initial values for Stan.
