How to consider rude(?) The modified Jeffreys interval is a modification of the Jeffreys interval for Our dataset has 150 observations (population), so let's take random 120 observations from it (large sample). a published work, please cite it as a source. Calories for males and females, are we justified in claiming that Intuitively, the more observations we have, the better our estimates will be.  B       420   data   = Data, y/n # observed proportion, p Also notice that as our sample size increased, the confidence interval narrowed down. The following code gives 'bias-corrected' approximate limits for f: (1.96/2-f^.5)^2 # lower 95% conf. The "logit" method fits a logistic regression model and computes a Wald-type interval on the log-odds scale, which is then transformed to the probability scale.. } # end of loop This also explains the confint () comment “Waiting for profiling to be done…” rev 2020.11.24.38066, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide.
