Initial mean/SD for primary parameter values

Source: R/PM_model.R
msd.Rd

[Stable]

Define primary model parameter initial values as mean and standard deviation, which translate to a range. The mean serves as the midpoint of the range, with 3 standard deviations above and below the mean to define the min and max of the range. For nonparametric, this range will be absolutely respected. For parametric, values can be estimated beyond the range.

Usage

msd(mean, sd, gtz = FALSE)

Arguments

mean

Initial mean.

sd

Initial standard deviation.

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 the range.
