Multiple matrix multiplication with two 3-dimensional arrays
...,i]
}
My question is :
Is there a more efficient way to do that computation, i.e. without a loop?
Maybe I could use an "apply" or something but I
can't figure out how. I would have hoped that simply doing
array1%*%array2
would work, but it doesn?t
Thank you very much!

glm convergence warning
Hi,
When I run the following code :
Y <- c(rep(0,35),1,2,0,6,8,16,43)
cst <- log(choose(42, 42:1))
beta <- 42:1
tau <- (beta^2)/2
fit <- glm(formula = Y ~ offset(cst) + beta + tau, family = poisson)
fit
fit$converged
glm prints a warning saying that the algorithm did not converge.
However, fit$converged takes the value TRUE.
I don't understand why fit$converged is not

With this package you can simulate several lines into the QQnorm-Plot
and the TA-plot under Gaussian distribution

http://crantastic.org/packages/stratification
This package performs univariate stratification of survey populations.
The main function implements a generalization of the
Lavallee-Hidiroglou method of stratum construction. The generalized
method takes into account a discrepancy between th...
