Dear all I am trying to fit Variable Coefficients Models on Unbalanced Panel Data. I managed to fit such models on balanced panel data (the example from the "plm" vignette), but I failed to do so on my real, unbalanced panel data. I can reproduce the error on a modified example from the vignette: > require(plm) > data("Hedonic") > Hed <- pvcm(mv ~ crim + zn + indus

Hello, I am trying to use the plm package for panel econometrics. I am just trying to get started and load my data. It seems from most of the sample documentation that I need to use the pdata.frame function to get my data loaded. However, even after installing the "plm" package, my R installation cannot find the function. I am trying to follow the example in plmEN.pdf (

Dear all, I would like to implement a spatial quantile regression using instrumental variable estimation (according to Su and Yang (2007), Instrumental variable quantile estimation of spatial autoregressive models, SMU economics & statistis working paper series, 2007, 05-2007, p.35 ). I am applying the hedonic pricing method on land transactions in Luxembourg. My original data set contains

Since I have a mixture of RH 7.1, 7.2, 7.3 and Advanced Server 2.1 boxes, I've made a set of RPMs for those platforms. I do not have a RedHat 8.0 box to make RPMs. Since RedHat <= 7.2 is out of support by RedHat, I don't think we'll see any officially created RPMs (but I could be wrong about that) so I thought I'd offer these to the general community. These were all built

hi - i just started using R as i am trying to figure out how perform a linear regression on a huge matrix. i am sure this topic has passed through the email list before but could not find anything in the archives. i have a matrix that is 2,000,000 x 170,000 the values right now are arbitray. i try to allocate this on a x86_64 machine with 16G of ram and i get the following: > x <-
