[R] prediction intervals for robust regression

2015-02-11 Thread Burns, Jonathan (NONUS)
I have created robust regression models using least trimmed squares and MM-regression (using the R package robustbase). I am now looking to create prediction intervals for the predicted results. While I have seen some discussion in the literature about confidence intervals on the estimates for

[R] Count of Histogram Bins using Shingles with lattice

2013-02-08 Thread Burns, Jonathan (NONUS)
I know that I can get a count of histogram bins in base R with plot=FALSE. However, I'd like to do the same thing with lattice. The problem is that I've set up shingles, and I'd like to get the count within each bin within each shingle. plot=FALSE doesn't seem to do it. [[alternativ
