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.
