Check if cached fit can be used. — brmsfit_needs

Checks whether a given cached fit can be used without refitting when file_refit = "on_change" is used. This function is internal and exposed only to facilitate debugging problems with cached fits. The function may change or be removed in future versions and scripts should not use it.

brmsfit_needs_refit(
  fit,
  sdata = NULL,
  scode = NULL,
  data = NULL,
  algorithm = NULL,
  silent = FALSE,
  verbose = FALSE
)

Arguments

fit: Old brmsfit object (e.g., loaded from file).
sdata: New Stan data (result of a call to standata). Pass NULL to avoid this data check.
scode: New Stan code (result of a call to stancode). Pass NULL to avoid this code check.
data: New data to check consistency of factor level names. Pass NULL to avoid this data check.
algorithm: New algorithm. Pass NULL to avoid algorithm check.
silent: Logical. If TRUE, no messages will be given.
verbose: Logical. If TRUE detailed report of the differences is printed to the console.

Value

A boolean indicating whether a refit is needed.

Details

Use with verbose = TRUE to get additional info on how the stored fit differs from the given data and code.
