11 Logistic Regression Output – Example 2 A credit card company wants to predict if an existing card holder will upgrade (success) or not using independent variables Purchases (in thousands) - the card holder's purchases from last year and Platinum Profile (1 if card holder fits credit card's policy; 0 if they do not fit policy) Find the Point Estimate Probability p($42.572,1) (Note: $42.572 is what we used when purchases were $42,572 in thousands. 1 means card holder fits policy) Find the Point Estimate Probability p($51.835,0) (Note: $51.5835 is what we used when purchases were $51,835 in thousands. O means card holder does not fit policy) Parameter Estimates Term Estimate Std Error 4.0818938 Intercept -9.9524146 Purchases 0.20983066 0.0907079 PlatProfile 4.14786846 1.6101814
