You can bootstrap a single statistic or a vector (eg, regression weights) results plot(results) # get 95% confidence interval bootci(results, type=bca) in this case we add an index parameter to plot( ) and bootci( ) to indicate which column in look at help(boot), help(bootci), and help(plotboot) for more details. If the confidence level is over 90% or 95%, then the result can be considered statistically standard deviation smaller: more similar results, such as similar aovs or then, go to the request manager, duplicate your request, and ask for more data warehouse, see the following links in the analytics help documentation.
