input: arima output: Arima,Trinidad and Tobago Population: city population | 34997 people my comment: Nothing about ARIMA time series models, which comes up as the 3rd link on Google. input: garch output: Wolfram|Alpha isn't sure what to do with your input. * Did you mean:march my comment: nothing about GARCH time series models, widely used in finance input: united states budget deficit output: -$347 billion per year (US dollars per year) (2005 estimate) my comment: Users would want more recent data, such as the 2008 deficit and the estimated 2009 deficit. Wolfram Alpha appears much less useful than the combination of Google and Mathematica, so I wonder if resources are better spent adding functionality to Mathematica.
