Forescasting using predict() in an object of class arimax when there is an outlier IO in the model.
...The object is a model of a time series in which I identified an IO oulier at the element 33 of the serie (using the function detectIO() from the package TSA in an object arimax that corresponds a model ARIMA(1,1,0) that not include the outlier) , so I incorporated this in the model ARIMA(1,1,0): mz3B<-arimax(z3B,io=c(33),order=c(1,1,0)) where the object z3B is a time series of class ts . When I want to use the predict() method, there is a problem, and a warning message is printed: > predict(mz3B,n.ahead=12) Error in dim(data) <- dim : Attempting to specify an attribute in a NULL So i...

Double integration - Gauss Quadrature
Hi, I would like to solve a double integral of the form \int_0^1 \int_0^1 x*y dx dy using Gauss Quadrature. I know that I can use R's integrate function to calculate it: integrate(function(y) { sapply(y, function(y) { integrate(function(x) x*y, 0, 1)$value }) }, 0, 1) but I would like to use Gauss Quadrature to do it. I have written the following code (using R's statmod package)
