The fitted (or estimated) regression equation is Log(Value) = 3.03 – 0.2 Age The intercept is pretty easy to figure out. It gives the estimated value of the response (now on a log scale) when the age is zero. We would estimate the value of a “new” Accord (foolish using only data from used Accords) as Log(Value for Age=0) = 3.03The logistic regression coefficients give the change in the log odds of the outcome for a one unit increase in the predictor variable. For every one unit change in gre, the log odds of admission (versus non-admission) increases by 0.002. For a one unit increase in gpa, the log odds of being admitted to graduate school increases by 0.804.Logistic Regression Calculator.
