Probability to ratio
WebbThe relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. Together with risk difference and odds ratio, relative risk measures the association between the exposure and the outcome.

The odds ratio of detection if an animal is on site for X minutes is calculated as follows.
An odds is the ratio of the probability of an event to its complement: odds ( X) = P ( X) 1 − P ( X) An odds ratio (OR) is the ratio of the odds of an event in one group (say, A) versus the odds of an event in another group (say, B ): OR ( X) A vs B = P ( X A) 1 − P ( X A) P ( X B) 1 − P ( X B) A probability ratio1 (PR, aka ... Visa mer Odds relate well to logistic models $$p = \frac{1}{1 + e^{-(a+bx)}}$$ Probability relates well to exponential models $$p = e^{a+bx}$$ Visa mer Let's see how the curves of these models compare to each other in the images below. 1. For small values of $p$ the difference between odds and probability is not … Visa mer Logistic models are more typical (or related shapes like logit models). This makes comparisons with differences in log-odds (or equivalent ratios of odds) … Visa mer
