WebExamples of Poisson regression. Example 1. The number of persons killed by mule or horse kicks in the Prussian army per year. Ladislaus Bortkiewicz collected data from 20 volumes of Preussischen Statistik. These data were collected on 10 corps of the Prussian army in the late 1800s over the course of 20 years. Example 2. WebMost people have trouble understanding the scale of the coefficients. For logistic regression, there is a simple trick: exponentiating the coefficient makes it an odds, like in: odds are 5:1 on a ...

Web1 Answer. Sorted by: 1. This model evaluates the log odds of detecting an animal at the site based on the time in minutes that the animal spent on the site. The model output indicates: log odds (animal detected time on site) = -1.49644 + 0.21705 * minutes animal on site. To convert to odds ratios, we exponentiate the coefficients: WebThe odds ratio for your coefficient is the increase in odds above this value of the intercept when you add one whole x value (i.e. x=1; one thought). Using the menarche data: exp (coef (m)) (Intercept) Age 6.046358e-10 5.113931e+00. We could interpret this as the odds of menarche occurring at age = 0 is .00000000006. aram barbershop
