WebMay 23, 2024 · Solution. First, note that the slope is the coefficient in front of the x. Thus, the slope is 14,329. Next, the slope is the rise over the run, so it helps to write the slope as a fraction: (2) S l o p e = r i s e r u n = 14, 329 1. The rise is the change in y and y represents student loan debt. Webthe rate of change in Y (the dependent variables) as X changes (as in the LP model or OLS regression), now the slope coefficient is interpreted as the rate of change in the "log odds" as X changes. This explanation is not very intuitive. It is possible to compute the more intuitive "marginal effect"
