I understand that the hat matrix is a function of the predictor variable alone. So, in the following example why do the values on the diagonal of the hat matrix change when I go from an unweighted fit to a weighted fit? Is the function hatvalues giving me something other than what I think it is? library(ISwR) data(thuesen) attach(thuesen) fit <- lm(short.velocity ~ blood.glucose)

I suspect that the line in the added variable plot (library car) is a SLR of the residuals, but I can't seem to find this written anywhere. Can someone confirm this? Thanks. Tom [[alternative HTML version deleted]]

  Dear R-helpers, hello I am seeking your help in somehow getting names of variables without quotes (" "). Let us say, we have a table with 3 variables V1, V2 and V3. After the table is read, I get names of the variables (thro' the following code) as under quotes (like "V1" rather than the original representation V1)

Dear R-users, I have an outcome variable and I'm unsure about how to treat it. Any advice? I have spending data for each county in the state of California (N=58). Each county has been allocated money to spend on any one of the following four categories: A, B, C, and D. Each county may spend the money in any way they see fit. This also means that the county need not spend all the money that

A sample graph of this is here: img213 imagevenue com/img php?image=48746_partial_plot_122_538lo jpg [replace spaces with dots, this bounces otherwise] I am unsure if this means anything or if it's built in (like a SLR going thru the mean of x an y). I should note that for this example I have assumed that the y-axis is not scaled somehow (see first question). Any insight appreciated. Thanks for your time. Christopher

Hi, for those of you who haven''t read: http://meyerweb.com/eric/thoughts/2006/05/08/flummoxed-by-frameworks/ ""Oh", they gush, "you should absolutely try Ruby on Rails! It''s so easy! It''s almost like writing regular English!" Which means they''re clearly on crack, because Ruby on Rails is so very different from a human-written language
