Autoregressive example with noise added to x data
Noise added to see effect on calculating for h = 5 (the lag in the data)
Allowed to calculate, but very small value (expected peak value)
Problem suspected to be with PDF estimation by Kernel method with high covariance
Still eliminating zero values
Still eliminating negative sum elements
The result appears to be very sensitive to amplitude bin selection, this can be due to the above mentioned manipulations - not sure if they are justifiable, but without it division by zero or negative transfer entropies result.
