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.

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.
