After building your model, you have to estimate it. You will use quantitative methods and statistical software for this purpose. Here are an econometric bibliography and some softwares to help you in your task.

Advice : please verify each assumption beyond the econometric method you use. For instance, ordinary least squares estimation suppose residuals independency. That's why you should verify this assumption when you use this method with time series by checking the Durbin-Watson test (about first order residual correlation and only for models without lagged dependent variable as exogenous variable). 

You should apply a large set of statistical tests to check the quality of your model. Econometric literature will supply you with a huge quantity of statistical tests. They are often available in your statistical software.

Econometric software

	Eviews Software available on the HEC's network. It would be very useful to read the software help (very well done). We can introduce you to the use of this software by reading our Eviews tutorial. But Stata is even better !!! In fact, the best econometric software in the world. Learn to use it through the UCLA "Stata" Web Page.
	TSP Very similar to Eviews but working on DOS instead of Windows. Software available on the HEC's network too.
	SPSS Statistical software availabe on the HEC's network.
	Microsoft Excel I'm sure you know it. This software is available on the HEC's network too.
	Webec Webec's links to statistical, econometric and economic softwares.
	Bill Goffe's statistical and computational software links Software links of the site Resources for the Economists on the Internet.
