[R] Bootstrapping One- and Two-Sample Hypothesis Tests of Proportion
Hi Bert, You mean, just compute the test specifying the mean as the parameter but using 1's and 0's for the data? Also I don't get how a proportion is a mean of 0/1 responses. Could you please elaborate? Thanks!

[R] Bootstrapping One- and Two-Sample Hypothesis Tests of Proportion
Hi, I don't see Duncan's reply in the archive, but consider:> 1 / 4[1] 0.25> mean(c(1, 0, 0, 0))[1] 0.25> 3 / 9[1] 0.3333333> mean(c(1, 1, 1, 0, 0, 0, 0, 0, 0))[1] 0.3333333 Regards, Marc Schwartz> On Nov 29, 2018, at 6:57 PM, Janh Anni <annijanh at gmail.com> wrote: > > Hi Bert, > > You mean, just compute the test specifying the mean as the parameter but > using 1's and 0's for the data?

[R] Bootstrapping One- and Two-Sample Hypothesis Tests of Proportion
Hi Marc, I see what you are saying. I will try re-running the* boot.two.per* function using 1's and 0's for the data and specifying mean as the parameter and see what happens. I will report back. Thanks so much for your kind assistance!
