Hello all, I ran my ANN model to train 60 training sets out which 42 were used for training, 9 used for validation and 9 were used for testing. This values were shown in 'nntraintool - > regression plots'. I tried to calculate them manually also and they were matching for divideblock function.
But same thing if I do for dividerand function with same ratio as used above then I am not getting the values of correlation which were displayed in 'nntraintool - > regression plots'.
Please help me regarding how to use dividerand in NN and use appropriate values for model evaluation.
Regards,

dividerand uses random indices.
Divide targets into three sets using random indices
So of course the values will be a little different.
