movfit: Optimization function that returns the squared difference between user
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.
