Description

Definition of prior distributions for standrc model parameters

Usage

  standrc_priors(b="normal(pb, 100)",
                 c="normal(pc, 100)",
                 d="normal(pd, 100)",
                 e="normal(pe, 100)",
                 f="normal(pf, 100)",
                 sy="inv_gamma(0.001, 0.001)",
                 sb="inv_gamma(0.001, 0.001)",
                 sc="inv_gamma(0.001, 0.001)",
                 sd="inv_gamma(0.001, 0.001)",
                 se="inv_gamma(0.001, 0.001)",
                 sf="inv_gamma(0.001, 0.001)",
                 pb=NULL,
                 pc=NULL,
                 pd=NULL,
                 pe=NULL,
                 pf=NULL)

Arguments

b	prior for the slope parameter (on log scale)
c	prior for the asymptote parameter
d	prior for the 2nd asymptote parameter
e	prior for the effective dose parameter
f	prior for the asymmetry parameter (on log scale)
sy	prior for the residual standard deviation
sb	prior for the slope random effect standard deviation
sc	prior for the asymptote random effect standard deviation
sd	prior for the 2nd asymptote random effect standard deviation
se	prior for the effective doserandom effect standard deviation
sf	prior for the asymmetry random effect standard deviation
pb	prior mean vector for the slope parameter (if NULL, it is drived from the data)
pc	prior mean vector for the asymptote parameter (if NULL, it is drived from the data)
pd	prior mean vector for the 2nd asymptote parameter (if NULL, it is drived from the data)
pe	prior mean vector for the effective dose parameter (if NULL, it is drived from the data)
pf	prior mean vector for the asymmetry parameter (if NULL, it is drived from the data)

Details

The priors are defined by character strings, containing stan code with the distributional assumptions for each parameter. pb, pc, pd, pe, pf contain the automatically derived prior means and can be replaced by supplying vectors for the arguments pb, ..., pf.
