Here is the results of linear regression analysis for Brain Tumors cases (76148 case) of all SEER data 1973-2011. The analysis test survival months as dependent variable and race, age, sex and treatment as independent variables. There is a warning message shows up when applying treatment as independent variable!!! and the treatment data are incomplete in results tables.
I've submitted the results of two analysis with and without treatment variable.
I'm waiting your feedback.
