Hi Jun,
I'd for a local fitting by means of the loess() function. Assuming z is the
third axis:
x-runif(25)
y-runif(25)
z-runif(25)
xyz.fit -
loess(z~x+y,control=loess.control(surface='direct'),span=.5,degree=1) #tune
parameters as you like
z.predict -matrix(predict(xyz.fit,cbind(x,y)),5,5)
if just integer exponentiation is enough, then I'd suggest:
expf - function(x, n) { return(prod(rep(x, abs(n)))^sign(n)) }
cheers.

I have been trying emacs with ess, Kate, plain gedit..nothing really
satisfied me..
but then I found a nice plugin for gedit: Rgedit !
it supports split screen with R terminal window (you can also personalize
colour if, like me, do like to
stick with old habits :) ), moreover gedit has a brackets
by myself? and if so, how can I extract what I
need from the model object?
thanks to everybody

Dear All,
does anybody know of a package (working under Linux) for multilevel IRT
modelling?
I'd love to do this without having to go on WINSTEPS or the like..
thanks for the attention!

I guess you could just use as an argument to sample
data[,-c(1,2)]
where 1 and 2 are id and pID50 column number

other routine which could deal with
categorical (along with non categorical) variables without for the aim of
optimization?
thanks in advance
