Dials parameter for symmetry type — sym_type

Returns a qualitative dials::new_qual_param() describing the sym_type argument of the psvr model specs. "none" fits the non-symmetric model; "even" maps to a = 1L (standard symmetric kernel); "odd" maps to a = -1L (anti-symmetric kernel).

Usage

sym_type_param(values = c("none", "even", "odd"))

Arguments

values: Character vector of levels to search over. Any subset of c("none", "even", "odd"); defaults to all three. Pass values = c("even", "odd") to tune over the symmetric models only, which reproduces the two-level grid offered before psvr 0.0.2.9011.

Value

A qual_param object.

Examples

sym_type_param()
#> Symmetry type (qualitative)
#> 3 possible values include:
#> 'none', 'even', and 'odd'
sym_type_param(values = c("even", "odd"))
#> Symmetry type (qualitative)
#> 2 possible values include:
#> 'even' and 'odd'
