Thanks Dr. Henningsen for the response. I got it to run with the code bellow: I do not know the reason why, thought.

library("micEcon")
library(plm)

setwd("C:\\Users\\Wahab\\Desktop\\production Econs")

dta <- read.csv("MTQ1DataQuad.csv", header=T)
prodt<-data.frame(dta)
Paneldat1 <- pdata.frame(prodt, index = c("Indiv","Time"))

xmat<-c( "n", "p", "k", "l")
quad <- quadFuncEst( "y", xmat ,paneldat1, shifterNames ="pdi")

I regret that the error message is not very helpful. I guess that one of your variables is not in the (panel) data frame. Plese check if the following commands all print the desired variables: paneldta1[[ "y" ]] paneldta1[[ xmat[1] ]] paneldta1[[ xmat[2] ]] paneldta1[[ xmat[3] ]] paneldta1[[ xmat[4] ]] paneldta1[[ "pdi" ]]

library("micEcon")
library(plm)

setwd("C:\\Users\\Wahab\\Desktop\\production Econs")

dta <- read.csv("MTQ1DataQuad.csv")
prodt<-data.frame(dta)
paneldta1 <- pdata.frame(prodt, index = c("Indiv","Time"))

xmat<-c( "n", "p", "k", "l")
quad <- quadFuncEst( "y", xmat ,paneldta1, shifterNames ="pdi", linear = FALSE, homWeights = NULL,
regScale = NULL )

Thanks
