Dear Gretl users,

I am trying to run a kernel approximation to a series of data (attached), using the command kdensity as show in the manual.

Specifically, the inp is as follows:

matrix d = kdensity(Water)
gnuplot --matrix=d --with-lines --output=pruba.eps

But, once run the output says that the second column has non finite values. Maybe is because values are integers, but I have checked on Stata (sorry, a friend of mine, I do not use it), and the kernel density flows without problems.

Is this a problem of the data, or I am doing something wrong?

Best
Leandro
