How can I predict future temperature data lets say (20 days) without coding from historical data? (multi-step prediction)

Hi All, How can I predict future temperature data lets say (20 days) without coding from historical data? (multi-step prediction) AS I know I will have 2 file of temperature (input and target) both have have historical temperature. How can I get the new 20 day without without coding? is it possible? Thanks

Use the autocorrelation function to help determine which feedback lags are significant. For example, search using

 greg nncorr

To predict beyond the domain of your current data

 1. Design an openloop nar with as many feedback lags as are significant.

 2. Close the loop so that the output(instead of the target) feeds back to the input (net--> netc).

 3. Run the data through netc. If performance is unsatisfactory, train netc using the openloop weights as initial conditions

You may have to use my doubleloop technique to find a good openloop design. Search with a subset of

 greg nar Ntrials closeloop netc

Hope this helps.

Thank you for formally accepting my answer

Not familiar with that Toolbox.

What do you mean without coding? You're not going to write any MATLAB code to do it? Like you will only use some published package or built-in utility to do your task?

[Greg Heath]

You did not answer Image Analyst's question.

What is "hit train percentage"?

[Greg Heath]

OK. But please do not use that term again.

[Image Analyst]

We don't know about the Wizard toolbox. Is that by the same Mathworks team that is working on the Crystal Ball Toolbox and the Mind Reading Toolbox?

You did not list any toolboxes in the "Products" section under your question so we don't know what toolboxes you're talking about. All I can gather is that you don't want to write code but want to operate some packages GUI utility in the toolbox and interact with it. Kind of like how you'd use any of the "Apps" listed on the "App" toolbar ribbon. Please attach a screenshot or two to illustrate what you are doing.

Oh!...

 hit is a verb, not an adjective!

and ...

 you want to do everything via GUI without using the command line.

Does Matlab really use the term Wizard?

[Greg Heath]

Using MATLAB 2011b:

>> lookfor wizard

 wizard        - Obsolete function
 uiimport      - Open Import Wizard to import data

>> help wizard

 wizard Obsolete function
    wizard is obsolete and may be removed from future versions.
    The replacement for this function is GUIDE.

   See also guide, inspect.

"What is the hit count?" - an example of using "hit" as an adjective rather than a verb.

"Has the count been hit?" - an example of using "hit" as a verb rather than an adjective.
