Covariates in fuzzy RDD with rddtools
Hello! I am having trouble including covariates in a fuzzy RDD model in R with rddtools. I run the following commands: library(rddtools) data.complete2 <- as.data.frame(cbind(GDPpc.rel, GR.rate, fitval.firstStage)) colnames(data.complete2) <- c("GDPpc.rel", "GR.rate", "FitTreat") data.RDD<-rdd_data(x=data.complete2\$GDPpc.rel,

R2 in multilevel modelling
Goodmorning everybody, i''m an italian statistician and i''m using R for research. Could someone tell me some indices to see the goodness of fit in multilevel modelling? I''m using the lmer function, and I want to know if my model fit well my data. I actually want to justify the use of multilevel model instead the classical one. Hope someone can help me. Thank you.

Persp plotting of kernel density estimate.
Dear All, I am trying to visualize the surface of a bivariate kernel density estimate. I have a vector of bivariate observations(x,y), and a function which computes the kernel density estimate z corresponding to each observation. I cannot generate the (x,y) data in the ascending order needed by persp(x,y,z). I was wondering whether there is an R version of the S function interp. Would anybody
