Re: [R] function indexed weighted log-rank statistics

Hi David, Thanks, survdiff actually only has the G(rho) family, i.e. gamma is set to 0. There is another package called surv2sample, that I found only after I sent out the email, that contains what I am looking for. Thanks, Ritwik On Wed, Sep 17, 2008 at 5:53 PM, David Winsemius <[EMAIL PROTECTE

The survdiff() function in the survival package does the G(rho) family (ie, G(rho, gamma=0)). -thomas On Wed, 17 Sep 2008, Ritwik Sinha wrote: Hi, Is there an implementation of the G(rho,gamma) class of function indexed weighted log-rank statistics in R? For example those mentione

Hi, Is there an implementation of the G(rho,gamma) class of function indexed weighted log-rank statistics in R? For example those mentioned in the paper by Kosorok and Lin (1999): The Versatility of Function-Indexed Weighted Log-Rank Statistics [JSTOR link : http://www.jstor.org/pss/2669706]. I wi
