Hi,
I am trying to create a power curve to show how the power of a t-test varies depending on the mean. Any ideas how I should go about this?

hurdle, simulated power
...parameter for negative binomial, infinity
correspond to poisson
#
#example power analysis
#return three power, power1 for zero part, power2 for negative binomial part
#power3 for joint test,significance level can be set, default is 0.05
#M is simulation time
#require pscl package
#library(pscl)
mypower <- function(n, beta0, beta1, alpha0, alpha1, theta,

data <- mysim(n,beta0,beta1,alpha0,alpha1,theta)
require(pscl, quietly = TRUE)
res <- hurdle(y ~ trt, data = data, dist = "negbin"...

pow__ii

I used to have endless trouble with __pow_ii which as I recall could be be
fixed by the correct incantation of the mix of compiler libraries and
LD_LIBRARY_PATH. It seemed to be extremely sensitive and never easy to get
right. The problem is
