Rcpp version of the Optimization function that returns the squared difference between user specified and calculated movement parameters.

The user specifies the probability of staying in the same area and spatial heterogeneity (both in the unfished state). This function returns the squared difference between these values and those produced by the three logit movement model.

Usage

movfit_Rcpp(par, prb, frac)

Arguments

par: Three parameters in the logit space that control the four probabilities of moving between 2 areas
prb: User specified probability that individuals in area 1 remain in that area (unfished conditions)
frac: User specified fraction of individuals found in area 1 (unfished conditions)

Details

This is paired with getmov to find the correct movement model.
