            This is what I think you're looking for. First, it isn't built into that plotting function to do this, but you can create these labels dynamically.

            It ended up being a bit easier if I changed the name of stratum to Quartile. If that's what you're labeling it, this shouldn't be too big of an issue.

            I think you mean to bootstrap sample from the grouped replicates, grouped by each Diversity category? bootstraps takes the whole dataframe as an argument to sample from. To borrow the code from the examples here, you could sample 5 random replicates from each Diversity category (with replacement) and for each bootstrap resampling extract the means of each category:

            R- How to conduct two-sample t-test with two different survey designs
            Asked 2022-Jan-12 at 07:34

            I want to perform a two-sample (welch's) t-test on the equality of two means, one of which is obtained using simple random sampling (srsmean), and the other which is calculated using survey weighting with the survey package (mean_weighted). I also conduct a t-test between mean_weighted and the mean obtained when weighting and stratification are both implemented in the survey design (mean_strat).

            I know there is a svyttest() function, however, as far as I can tell, this function only tests the means of two samples within one survey design, not means obtained with different survey designs.

            I also tried using rnorm to create fictional samples eg c(rnorm(9710, mean = 156958.8, sd = 364368)), but the problem with this approach is that in complex sampling methods like stratification, the effective n is usually smaller than the nominal n, and so I am unsure what to put as n. Additionally, this method feels a bit contrived, as I would be fitting the data to a particular type of distribution.

            Finally, I tried writing out the equation for a t-statistic myself, however, in calculating the "standard error of the difference of means" involving a complex survey design, I also run into problems related to the "effective sample size."

            Is there another approach that would work for both the t-test between srsmean, mean_weighted AND the t-test between mean_weighted, mean_strat?

            Answered 2022-Jan-12 at 07:34

            i'm confused about the purpose of a t-test between your mean_weighted and mean_strat since the difference between those coefficients will always be zero? i might compare the simple random sample against the complex design like this?
