Initial range for primary parameter values

Define primary model parameter initial values as range. For nonparametric, this range will be absolutely respected. For parametric, the range serves to define the mean (midpoint) and standard deviation (1/6 of the range) of the initial parameter value distribution.

Usage

ab(min, max, gtz = FALSE)

Arguments

min

Minimum value.

max

Maximum value.

gtz

Greater than zero. If FALSE (default), ensure parameter values remain positive by discarding negative values. Only relevant for parametric analyses, since lower limit of parameter values for nonparametric are strictly controlled by ab.
