sample size for survival curves
Dear R users, I am not asking questions specifically on R, but I know there are many statistical experts here in the R community, so here it goes my questions: Freedman (1982) propose an approximation of sample size/power calculation based on log-rank test using the formula below (This is what nQuery does): (Z(1-?/side)+Z(power))^2*(hazard.ratio+1)^2 N = --------------------------------------------- (2-p1-p2)*(hazard.ratio-1)^2 Where Z is the standard normal cumulative distribution. p1 and p2 are the survival probability of the 2 groups at a given time...

[PATCH libnbd 0/5] info: --map: Coalesce adjacent extents of the same type.
This adds coalescing of adjacent extents of the same type, as mentioned by Eric Blake in the commit message here: https://github.com/libguestfs/libnbd/commit/46072f6611f80245846a445766da071e457b00cd The patch series is rather long because it detours through adding the <vector.h> library from nbdkit into libnbd and replacing ad hoc uses of realloc, char ** etc in various places. Rich.

Package for sample size calculation
Dear list, Is anyone aware of a library for sample size calculation in R, similar to NQuery? I have to give a course in this area, and I would like to enable the students playing around with this. Best wishes, Matthias

[PATCH libnbd] api: Allow NBD URIs to be restricted.
New APIs are added which let you enable or disable features of NBD URIs, mainly for security reasons. tls-psk-file is *disabled* by default for obvious security reasons. All other features are enabled by default. --- generator/generator | 127 +++++++++++++++++++++++++++++++++++++++++++- lib/handle.c | 26 +++++++++ lib/internal.h | 5 ++ lib/uri.c | 31 +++++++++--

[PATCH libnbd] api: Allow NBD URIs to be restricted.
Previous discussion: https://www.redhat.com/archives/libguestfs/2019-August/msg00102.html Last night I experimentally added support for URIs that contain the query parameter tls-psk-file, as part of rewriting the tests to cover more of the URI code. So you can now have a URI like: nbds://alice@localhost/?tls-psk-file=keys.psk However there's an obvious security problem here because now

[libnbd PATCH 0/2] Tighten URI parser
I'm not sure whether we want to go with just the first patch (reject nbd:unix:/path but still accept nbd:/path), or squash the two in order to go with the second (reject both abbreviated forms, and require scheme://...). Either way, though, nbdkit -U - --run '$nbd' will now error out rather than inadvertently connect over TCP to localhost:10809 instead of the intended Unix connection
