boxplot notches
Dear list members, Can anyone tell me how the notches in boxplot(Y~X,notch=T) are calculated? What do these notches represent exactly? I?d suppose they are Conficence Intervals for the median, but I?ve also been told they might show Least Significant Difference (LSD) equivalents. I would very much appreciate any help from you. Best regards Chris.

confidence intervals
Hello, I wonder if anyone has a function for calculating confidence intervals for ratios. I have mortality rates calculated for several groups from sample data -- but these can be treated as ratios?). I am entertaining the idea of bootstrapping them. Any help would be greatly appreciated. TIA, Marwan ---------------------------------------------------------------------------- ------------
