Standard error of log relative risk

WebbFitting a log binomial model to binary outcome data makes it possible to estimate risk and relative risk for follow-up data, and prevalence and prevalence ratios for cross-sectional data. However, the fitting algorithm may fail to converge when the maximum likelihood solution is on the boundary of the allowable parameter space. WebbHere, “σM ” represents the S.E. of the mean, which is also the S.D.

And because the robust variance estimator is not required, model-based standardization will not be as affected by small sample sizes.

Webb24 juli 2007 · In these examples, the "ground truth" is typically given as variable 1 while some estimator of the ground truth is given as variable 2. The relative risk is defined as the ratio of the probability of "success" probabilities, that is. relative risk = { N11 / ( N11 + N21 )}/ { N12 / ( N12 + N22 )} The relative risk is a useful statistic when ... WebbThe standard errors of the log relative risks are also computed and saved in variable S. The OUT= data set is structured to have one observation per response level for each input observation. As a result, the LogRR data set has three times as many observations as the input data set, School.
