Usage eexp (x, method = "mle/mme", ci = FALSE, ci.type = "two-sided", ci.method = "exact", conf.level = 0.95) Arguments Details WebThe confidence interval tells you how confident you are in your results. With any survey or experiment, you’re never 100% sure that your results could be repeated. If you’re 95% sure, or 98% sure, that’s usually considered “good enough” in statistics. That percentage of sureness is the confidence interval. Confidence Interval For a Sample: Steps
