ask a question in statistics
I have a question in regression analysis
In regression analysis the coefficient of determination (R^2) is good (0.8). That means 80% correlation exists between dependent & independent variables. But, acual Y values & predicted Y values (dependent variable is Y that is to be estimated) many values of predicted Y are not in the range of 80% of that of actual Y values i.e. many predicted Y don't lie in between limits 0.8*Yactual to 1.2*Yactual. So, for good results, what we should look for, how many predicted Y's (in percentage)should lie in what limits (like 80% as stated above)? I'm really confused. So, please help me. |
