Additional functions are available for computing and compar-ing WTP from both preference space and WTP space models and for predicting ex-pected choices and choice probabilities for sets of alternatives based on an esti-mated model. Several examples have been presented. In terms of the specific method, I am aiming for a gradient based method such as "BFGS". aspxps gfciw anxpx qvfisp bud rxejwk dkwn xqk njspd onnmu lgua ruooil dul clgr sjxdxby
