Multiplier to scale prior variance

Specification

Alias: none

Argument(s): REAL

Default: 1.0

Description

The initial proposal covariance will be given by the prior variance times the multiplier.

Default Behavior When using prior-based proposal covariance, the default is to use the prior variance for the proposal (multiplier = 1.0)

Usage Tips

The prior variance may result in too tight or narrow a proposal covariance. The multiplier can be used to scale all entries of the prior variance in determining the initial proposal covariance.

Examples

method
  bayes_calibration queso
    samples = 2000 seed = 348
    dram
    proposal_covariance prior
      multiplier 0.1
