extract_posterior_parameter {makemyprior} | R Documentation |
Extract the posterior parameter estimate of a random effect variance or fixed effect coefficient when inference is done with Stan
extract_posterior_parameter(obj, param)
obj |
An object from |
param |
Name of the variance parameter, which is the same as the name of the corresponding fixed or random effect in the data. Intercept is denoted 'intercept', and residual variance is denoted 'eps'. |
Returns a vector with the posterior samples of the chosen parameter, on variance scale for variances parameters and original (the common) scale for fixed effect coefficients
