compute_p_si function

Compute choice probabilities at posterior samples

This function computes the probability for each observed choice at the (normalized, burned and thinned) samples from the posterior. These probabilities are required to compute the WAIC and the marginal model likelihood mml.

compute_p_si(x, ncores = parallel::detectCores() - 1, recompute = FALSE)

Arguments

• x: An object of class RprobitB_fit.
• ncores: This function is parallelized, set the number of cores here.
• recompute: Set to TRUE to recompute the probabilities.

Returns

The object x, including the object p_si, which is a matrix of probabilities, observations in rows and posterior samples in columns.
