	              Number of Variables in Regression Analysis?

                In a cross-sectional study for regression analysis, how many observations should at least be used?
            
                  	Optimal Number of Variables in Regression Analysis
devarakonda srikanth, Member
For an effective regression analysis, there are no minimum numbers that are to be used. 

We need to list all independent variables that can affect our equation. The more independent variables we find, the better will be the outcome, as our analysis will have chopped all insignificant independent variables. 

This will give clear picture, and we can try to work on these variables for a successful outcome.
