WebSep 12, 2024 · where we still have our axis intercept, in addition to five independent variables and their respective coefficients. It is technically true that we can easily interpret our coefficients b1 through b5 in the same way as for a singular regression, however, this requires some assumptions that aren’t always perfectly true for data in the real world. . …
WebFor example, the second row shows that the AgeChild‘s exponentiated coefficient is 2.89, which means that a child has 2.89 times the survival odds of an adult, with a 95% CI of [1.79, 4.67]. Note: You should ignore the standard errors in this output since these are on the original scale while the coefficients are on the exponential scale.
