Convert SAS NLMIXED code for zero-inflated gamma regression to R
I'm trying to run a zero-inflated regression for a continuous response
variable in R. I'm aware of a gamlss implementation, but I'd really like to
try out this algorithm by Dale McLerran that is conceptually a bit more
straightforward. Unfortunately, the code is in SAS and I'm not sure how to
re-write it for something like nlme (if at all possible - with conditions
etc). Does anyone know both languages enough to try translating it? Would
very much appreciate your help!

Orthogonal Polynomial Regression Parameter Estimation
Dear all,
Can any one tell me how can i perform Orthogonal
Polynomial Regression parameter estimation in R?
--------------------------------------------
Here is an "Orthogonal Polynomial" Regression problem
collected from Draper, Smith(1981), page 269. Note
that only value of alpha0 (intercept term) and signs
of each estimate match with the result obtained from
coef(orth.fit). What
