This page reveals about those who want to solve problems using a set of tool kits.
Problem solvers who need to test their data by studying the cross section of a data should use STATA.
For those who want to use STATA effectively can use the following website: http://www.ats.ucla.edu/stat/stata/
Problem solvers who need to test their data by studying the time series characteristics of a data should use Eviews.
For those who want to use Eviews effectively can use the following website: http://www.hkbu.edu.hk/~billhung/eviews.html
Problem solvers who want to know what are the possible scenarios under a series of variables can simulate the possibilities by using the following software:
