Resampling to find Confidence intervals
...d "do" operators are functions specific to a workspace that comes with the book, not a normal R setup. So I was thinking of ways I could achive the same result, or sort of result because the resample should be different each time, I think the following would work to the same effect: resampled_ecoli = sample(ecoli, 500, replace=T) coefs = (coef(lm(MIC. ~ 1 + Challenge + Cleaner + Replicate, data=resampled_ecoli))) sd(coefs) And then I can work out confidence intervals by multiplying the standard errors by 2. Although I'm not used to doing this sort of operation in R so I don't wan...
