Hi R-Masters
I need use a sequential approach in serie of cases, but may data is not
normal.
If data is normal distribution is very easy create analysis using
likelihood ratio like of Wald test.
But in my case I need use a non-parametric test (Mann-Whitney).
I was use: RSiteSearch("sequential rank test") but not solve my
problem.
Do you know routine or package implement sequential rank test in R?
Thanks in advance

I looked for the same topic today and found ?wilcox.test in the stats package.

Hi Bernardo, I think that ?wilcox.test will help you. -- Henrique Dallazuanna Curitiba-Paraná-Brasil 25° 25' 40" S 49° 16' 22" O On 27/08/07, Bernardo Rangel Tura <tura@centroin.com.br> wrote:> > Hi R-Masters > > > I need use a sequential approach in serie of cases, but may data is not > normal. > > If data is normal distribution is very easy create analysis using > likelihood ratio like of Wald test. > > But in my case I need use a non-parametric test (Mann-Whitney). > > I was use: RSiteSearch("sequential rank test") but not solve my > problem. > > Do you know routine or package implement sequential rank test in R? > > Thanks in advance > > > -- > Bernardo Rangel Tura, M.D,Ph.D > National Institute of Cardiology > Brazil > > ______________________________________________ > R-help@stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >[[alternative HTML version deleted]]
