This keyword indicate number of network in ensemble that will
be analyzed. This allows to estimate variance of neural network predictions
for the whole data set and for each data entry.
The result of calculation is simple average of all networks. The
program also estimates variance of RMSE of all networks in the ensemble.
It recalculates neural networks with RMSE error that is higher than 3 standard
deviations from the average RMSE.
We recommend to use ENSEMBLE of 100-400 neural networks. A smaller
number provides a high error of neural network results, while a larger
number requires too long calculations.
The range of this keyword is [1,10000] and default value is {200}.
