I'm wondering how odds ratio is computed. I thought that it is (n11/n12)/(n21/n22), but it is not what fisher.test() computes. Could somebody let me know? > n11=3 > n12=1 > n21=1 > n22=3 > > n1_=n11+n12 > n2_=n21+n22 > > n_1=n11+n21 > n_2=n12+n22 > > x=rbind(c(n11,n12),c(n21,n22)) > > threshold=dhyper(n11,n1_,n2_,n_1) > probabili...

...a function that combines all the values from the dataset in order to produce the xi, xi*xj, xi*xj*xk values. The variables can take values in different ranges so I need that the function controls the scale. After that I would apply the regression to the obtained dataset. Example X1 X2 n11 n12 n21 n22 n31 n32 -> X1 X2 X1*X2 n11 n12 n11*n12 n21 n22 ... n31 n32 ... Is there any function like this in which, in addition of the above mentioned, I can specify the degree of combination? Thanks for your help, Miguel

I have been trying to determine the size of the R user base, and was asked to share my findings with this mailing list. Although I still don't have any definite estimate of this number, I do have some interesting and indicative information: 1. It appears that there are about 100,000 S-PLUS users. Rationale: According to Insightful's 2002 Annual Report, over 100,000 people use

...ms that it is meant for two groups such as reference/control versus cases. This is the sample of data in each of the two groups: Treatment_stat Death MonthsToEvent 1 0 60.0 2 1 55.3 0 1 36.7 0 1 39.9 number of cases in treatment strata : group 1: n12=110; n11=25;n10=15 (N2=150) group 2: n22=43;n21=8;n20=9 (N2=60) Coxph output indicates significant different survival in group 1 data but not in group 2. How can one be sure that the lack of significance of survival difference is true in group 2 and it is not because of fewer number of cases in group 1 ? Is there any function for this type of...
