...d again on the three models. I expect that the p.value for the comparison of model 1 and model 2 would remain the same, whether or not I add a third model to be compared with. However, the P values change, and I do not understand why. Here is an example code (following with it's input): data(barro) fit0 <- rq(y.net ~ lgdp2 + fse2 , data = barro) fit1 <- rq(y.net ~ lgdp2 + fse2 + gedy2 , data = barro) fit2 <- rq(y.net ~ lgdp2 + fse2 + gedy2 + Iy2 , data = barro) anova(fit0,fit1,fit2, R = 1000) anova(fit0,fit1, R = 1000) Output: > data(barro) > fit0 <- rq(y.net ~ lgdp2...

Dear R users, I would like to know if there is a way to increase the for() loop speed because in my routine the calculations are too slow. Best regards.

Music data is absolutely untouched, however, can this be an architecture difference between the compilers that made the Win32 and ELF executables? Just for the record, what is exactly making the files different? Thanks a lot. -- Djeizon Barros <djzn.br at gmail.com>

Hi All, I am trying to build a composite plot, with multiple categories, using ggplot2. In principle, it could be done using facetting, but I do not seem to be able to get past the defaults, so I try building each plot separately, then putting them all together using frameGrob and placeGrob. For this, I need to know how to: 1) format the legend with a different layout (e.g 2 rows by 2 columns,

Hi, Is there any way to estimate a DEPENDENT variable through a GLM/LM model? Suppose I have the linear model: y=a0+a1*x1+a2*x2 (a0=1, a1=0.6, a2=0.8, x1~N(1,1), x2~N(0,1)). The alphas and the auxiliary variables are given and I have to estimate y. The point is if I estimate it, let¹s say algebraically, I get high variances that do not decrease as sample sizes increases... Is the any other way

Dear All, When I run rlm to obtain robust standard errors, my output does not include p-values. Is there any reason p-values should not be used in this case? Is there an argument I could use in rlm so that the output does include p-values? Thanks in advance, Celso [[alternative HTML version deleted]]
