[R] R for reliability analysis (with censored samples)?
Hello, first: I am a newbie to this list, so if this isn't the right place to ask, thanks for pointing me to the right direction... I'm currently working on adding a degree in RAMS engineering to my general engineering education, and consequently I'm looking for software to get my future work done. This will have to handle mostly right-/left-/intervall-censored samples, which seems to be a non-trivial feature from what I've read and heard so far. Apart from this, RAMS work will be only part of my job and I will be the only one to do RAMS work in the (tiny) company I work for, so paying multi-kEUR every year in license fees for some commercial application will probably not be the preferred choice for us. So I'm planning to use R together with Python and GNUmeric/OO Calc instead. So here are the questions: How suitable is R for this kind of work (reliability analysis)? Does it handle (right-/left-/interval-)censored samples by default? Are there any information sources (on- or off-line) dedicated to the use of open-source software for reliability analysis and especially R? TIA, Sincerely, Wolfgang Keller -- P.S.: My From-address is correct
