Start by reading the documentation and try to reproduce the timeseries forecasting examples. Additional information can be obtained by searching the Newsgroup using the search words
timeseries and/or forecasting.
Hope this helps,
Greg

hello sir,
i am using nntool of matlab for my prediction my application is to forecast water demand based on previous consumption.
year month day net supply
2003 1 1 2900
2003 1 1 2915
.
.
2010 12 31 3400.
my input matrix has 3 inputs month day and date and output matrix is simply net supply.i have trained my network using
nntool i got good results in training,validation and testing.ie(0.93).but when i try to simulate the network using nntool to forecast the consumption
for 2011 year i am not getting good results.
i mean if the actual consumption on 1st jan 2011 is 3400 i am getting it as 2900.
can you give me any sugession how to improve the results.
