I guess this is the 95% confidence region, but I think I’m wrong, because there is no word related to 0.95 or 0.05 or any other number. I’m confused about it and … WebbUse Interval Plot to assess and compare confidence intervals of the means of groups. An interval plot shows a 95% confidence interval for the mean of each group. An interval plot works best when the sample size is at least 10 for each group. Usually, the larger the sample size, the smaller and more precise the confidence interval.

Webb15. Bootstrapping refers to resample your data with replacement. That is, instead of fitting your model to the original X and y, you fit your model to resampled versions of X and y for multiple times. Thus, you get n slightly different models which you can use to create a confidence interval. Here is a visual example of such an interval. Webbplot it can produced and points out the pitfalls those programming the procedure should consider.
