Hi,
I am translating some Gauss code to R. Gauss has an interesting way of
handling constraints. Observe the following code snipplet:
e1 = x[.,23] .eq 0; @ remove obs with Regular Hours = 0 @
e2 = x[.,12] .gt 1; @ remove obs with non-regular work status @
e3 = x[.,4] .lt 15;@ remove obs
Dear helpers,
I am wondering if I can use the growth package to fit continuous ARMA
time series. To be specific,
y <- arima.sim(model=list(ar=c(1.7,-0.8)),n=100)
How do I use carma to fit y if possible? The package is for longitudinal
data but I suspect I can use it for my problem. I looked at t

I use R on a dual Opteron running SuSE Enterprise version 8 (amd-64).
It compiles without complaint using gcc-3.3 (64bit)---all of the tests
are successful and my personal test code performs well. The
performance is rather good. I could NOT get R to compile using the

It is not really clear what you want, since what you call the

so its integral is infinite.

I don't know about doing it all on the same line, but have you
considered something like the following:
DF <- data.frame(x=1:9, y=1:9, z=rep(1:3, 3))

HoltWinters() by default fits a seasonal model, and therefore needs
three complete cycles for the starting values. But your third cycle is
incomplete, so in short, you haven't got enough data to fit a seasonal

I am wanting to construct a probability distribution for height and then,

These are the commands I have developed so far:
