a strange problem with integrate()
...the simple integral, but:
> integrate(g2,-2,2,theta=c(-2,3),xi=c(1,2,5,6),yi=c(1,0,1,1),sigma2=1)
Error in integrate(g2, -2, 2, theta = c(-2, 3), xi = c(1, 2, 5, 6), yi =
c(1, :
evaluation of function gave a result of wrong length
>
I have checked the integrand function
> valori<-seq(-2,2,l=30)
> risvalori<-NULL
> for(k in valori)
risvalori[length(risvalori)+1]<-g2(k,theta=c(-2,3),xi=c(1,2,5,6),yi=c(1,0,1,1),sigma2=1)
> plot(valori, risvalori)
And the integral exists..
Please, any comment is coming?
many thanks,
vito

"error using packet 1"
Hello,
I'm Giovanni from ROMA..
I can't find a solution for the error:
"error using packet 1
the y field is not specified and it has not a default value"
(this is my traslation from italian language)
The code is:
pc<- qqmath(~valori,
distribution=function(p) qweibull(p,beta,alpha),
prepanel = prepanel.qqmathline,
panel = function(x, y) {
panel.grid()
panel.qqmathline(y, distribution = function(p)
qweibull(p,beta,alpha))
panel.qqmath(x, y)

If I exclude I(eta^2) from the estimation I can do summaries: but
I need also I(eta^2) in order to compare this model with the same

Can you please help me or give me an hint?

ActiveRecord::StatementInvalid (invalid date) with Oracle
Hello all. I am a novice Ruby on Rails programmer, starting my first
project using a legacy Oracle 10 database. Using ''reverse_scaffold'' I
have created the models/controllers/views for my existing Oracle
tables.
All seems to work well, using /model/index, /model/show for most of my
tables, *except* when one of the tables contains a Oracle ''date''
column, for
