WebJun 20, 2015 · For "EXP (Coef)", you should compare its "distance" from 1 (odds ratio = 1 means independence). The larger, or smaller the number to 1, the stronger the correlation is. For the second question, "EXP (Coef)", i.e., (estimated) odds ratio, is of course always positive regardless the "Coef" is positive or negative. WebThe coefficient returned by a logistic regression in r is a logit, or the log of the odds. To convert logits to odds ratio, you can exponentiate it, as …

Here is an example of calculating the odds ratio for 1, 2, and 3 units of change. unit.change = c (1,2,3) exp (coef (model) ["exposure"]*unit.change) Share. Improve this answer.
WebAug 6, 2015 · 3 Answers. Sorted by: 40. You need a model to fit to the data. Without knowing the full details of your model, let's say that this is an exponential growth model , which one could write as: y = a * e r*t. Where y is your measured variable, t is the time at which it was measured, a is the value of y when t = 0 and r is the growth constant. WebWith Cox models, the linear combinations of factor levels for other contrasts and statistical tests will be taken on the coefficients themselves, not on the hazard ratios. In Cox model coefficients add; hazard ratios multiply. One final warning: there is a technical meaning of "frailty" in survival analysis that might lead to further confusion.
