いろいろ odds vs probability 241673-Odds vs probability logistic regression

RISK AND ODDS DEFINITIONS "Risk" refers to the probability of occurrence of an event or outcome Statistically, risk = chance of the outcome of interest/all possible outcomes The term "odds" is often used instead of risk "Odds" refers to the probability of occurrence of an event/probability of the event not occurringOdds vs Probability A good way to understand the difference between odds and probability is to imagine rolling a die and hoping to land on a two The odds of rolling the two are 1 to 5 One representing the chance of landing on the two, and five representing the alternative possibilities of landing on one of the other sides The probability Odds The relationship between x and probability is not very intuitive Let's modify the above equation to find an intuitive equation Step1 Calculate the probability of not having blood sugar Step2 Where p = probability of having diabetes 1p = probability of not having diabetes You can interpret odd like below

Once you have experiments with different durations, different dropout patterns or different event time distributions, a hazard ratio might be constant across experiments and is probably the better relative risk measure, but an odds or risk ratio will essentially never be (even if the hazard ratio is, while the same odds ratio would correspond to different hazard ratios across experiments) Hazard ratio = (hazard rate in intervention group) / (hazard rate in control group) The hazard ratio interpretation is a little clunky It tells you the risk of an event in the intervention group compared with the control group at any particular point in time The relative risk is different from the odds ratio, although the odds ratio asymptotically approaches the relative risk for small probabilities of outcomesIf IE is substantially smaller than IN, then IE/(IE IN) IE/IN Similarly, if CE is much smaller than CN, then CE/(CN CE) CE/CN Thus, under the rare disease assumption = () () = In practice the odds ratio is
