Inverse of exponential parameter transformation

Description

Inverse of transform1 for the purpose of deriving initial values.

Usage

transform1.inv(params, index.t=1:length(params), lowlimit=rep(0,length(index.t)), ... )

Arguments

params	full input parameter vector
index.t	indices of parameters to be transformed (default all)
lowlimit	lower limits to be applied (default zero), where the k-th component of lowlimit is applied to the k-th index in index.t
...	not used

Value

Transformed parameter vector.

Examples

params <- c(.1, .5, 1) # Desired initial values on original scale
transform1.inv(params, lowlimit=c(0, -1, 1)) # Initial values to use on transformed scale
