The econometric analysis consist of the estimation of the GMM, least square, and maximum likelihood among others. One software that can be very helpful in the econometric analysis is Gretl.
Gretl comes with all these analysis features already integrated. This integration is good for saving you lots of time. You can add your own sample data in order for Gretl to generate the analysis. The inclusion of a script for the generating of random is another possibility. Gretl is so advanced that it can plot the numbers for you to see.
The data and analysis resulted can be saved to an Excel or CSV file. The editing of the output model is yet another concept you will be able to control. Other well known simulations such as the Monte Carlo simulation can be used with Gretl.
