Specification

  • Alias: None

  • Arguments: REALLIST

Description

Shape of the prior distribution for calibrated error multipliers. Either a single value or number of hyper-parameters values may be specified.

Default: 102.0 (with beta = 103.0) so mean and mode are approximately 1.0 and standard deviation is about 0.1.
