movfit:
Optimization function that returns the squared difference between user specified and calculated movement parameters.
Description
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(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.
