problem with optim and integrate
Dear all,
I want to min "integrate( (p1*dnorm+p2*dnorm+p3*dnorm)^(1.3))" for p, mu,
and sigma.
So, I have to estimate 8 parameters(p3=1-p1-p2).
I got this warning-"Error in integrate(numint, lower = -Inf, upper = Inf) :
non-finite function value."
My questions are
How could I fix it? I tried to divide into several intervals and sum up, but
I got same message.
My code is
-----------------------------------------------------------------------------------
alpha=1.3; theta0=c(...

2) what are these warning messages?

integration error when I use "optim" and "integrate" simultaneously
Dear R users,
When I use two functions, 'optim' and 'integrate', simultaneously, I always
get an error like this
--------------------------------------------------------------------------
numint = function(z) {
dlnorm(z,mu[1],sqrt(exp(g[1]))) *
dnorm((z-mu[2])/sqrt(exp(g[2])))/sqrt(exp(g[2]))
}
integrate(numint,lower=0,upper=Inf)$value
Error in integrate(numint, lower = 0, upper = Inf) : non-finite function
value

[PATCH 00/21] Upgrade to Lua 5.2.2, add filesystem module and get_key binding
Hi,
This series targets automatic boot menu generation, but most of it
is the Lua upgrade, because I got tired reading deprecated API docs.
It's mostly a straightforward forward port of the earlier Syslinux
specific changes to Lua 5.1, except that:
* I chose the add a stub getenv() implementation to the COM32 API
instead of #ifdefing out all the references in Lua, and
* I kept oslib
