npreg: plotting out of sample, extremely large bandwidths
...better?
Many thanks in advance for any help with these issues.
The simulated example follows below. I am not sure if this is relevant
but I am using R 2.13.1 via RStudio 0.94.102 on a Windows 7 64-bit PC.
The version of the np package is 0.40-9.
rm(list=ls())
library("np")
set.seed(1)
num_obs <- 400
# generate data
x1 <- runif(num_obs,min=0,max=1)
x2 <- runif(num_obs,min=0,max=1)
e <- rnorm(num_obs,0,1)
y <- x1^2 + x2^2 + x1*x2 + e
mydata <- data.frame(x1=x1,x2=x2,y=y,e=e)
summary(mydata)
rm(x1,x2,y,e)

days between dates
Hello, I have some unbalanced panel data that is measured on weekdays only
(i.e., excluding Saturday and Sunday). I would like to get the number of
days between dates such that the number of days between a Friday and a
Monday is 1 (and not 3). Here is some code to illustrate my problem:
library('Hmisc');
DATE <-
