Constraint on one of parameters.
...t of parameters and want to set a
constraint on only one parameter. Here is my function. What I want to do is
estimate the parameters of a bivariate normal distribution where the
correlation has to be between -1 and 1. Would you please advise how to
revise it?

Reproducibility issue in gbm (32 vs 64 bit)
...on this example, it looks like the relative importance of 2 perfectly
correlated predictors is "diluted" by half in 32-bit, whereas in 64-bit, one
of these predictors gets all the importance and the other gets none. I found
this interesting.
### Sample code
library(gbm)
set.seed(12345)
xc=matrix(rnorm(100*20),100,20)
y=sample(1:2,100,replace=TRUE)
xc[,2] <- xc[,1]
gbmfit <- gbm(y~xc[,1]+xc[,2] +xc[,3], distribution="gaussian")

gamm in mgcv random effect significance
...(y), computed from a
behavior either observed or not out of 10 trials per time point. Hence I
use binomial (I believe quasi-binomial is not available in gamm). Each
of the nine series has an average of 30 observations give or take (total
264 observations), some under treatment (z) and some not. xc is centered
session number, int is the z*xc interaction. Based on prior work, xc is
also smoothed
Consider, for example, two models, both with AR(1) but one allowing a
random effect on xc:
g1 <- gamm(y ~ s(xc) +z+ int,family=binomial, weights=trial,
correlation=corAR1())
