primary_scales
Characteristic values to scale each calibration term
Specification
Alias: calibration_term_scales least_squares_term_scales
Arguments: REALLIST
Default: 1.0 (no scaling)
Description
Each real value in primary_scales
is a nonzero characteristic value
to be used in scaling each calibration term. They only have effect
when the associated method specifies scaling
.
Length: When specified, primary_scales
must have length one of:
One (the single value will be applied to each primary response); or
Number of response groups (
calibration_terms
), so the number of scalars plus the number of fields when fields are present; orTotal number of response elements, so the number of scalar responses plus the sum of the lengths of the fields.
Usage Tips:
Calibration only supports value-based scaling. Use scale values of 1.0 to selectively avoid scaling a subset of response functions.
Weights are applied as multipliers, scales as charateristic values / divisors.
When scaling is active, it is applied to calibration terms after any
residual formation (accounting for experimental data and optionally
measurement error covariance), and before any weights. See the
equations in calibration_terms
.
See the scaling information under specific methods, e.g.,
method-*-scaling
