Dear R users, I want to calculate the bias and variance of an estimator for several values of two parameters a and b. For example : b1 b2 a1 bias bias variance variance a2 bias bias variance variance Can one do array of arrays ? I have tried and it did not work. Actually I would like to get this array for several values of the number of observations. That would be an array of arrays of arrays :-) Maybe there is a better way to do that... Is there also a way to export arrays to Latex ? Thank you very much [[alternative HTML version deleted]]
Is it possible to have one array for bias and one for variance? such as.. biasAr b1 b2 a1 bias bias a2 bias bias and varAr b1 b2 a1 var var a2 var var then you can combine the two in a data frame? thanks y Michael Prince wrote:> > Dear R users, > > I want to calculate the bias and variance of an estimator for several > values > of two parameters a and b. > > For example : > > b1 b2 > a1 bias bias > variance variance > a2 bias bias > variance variance > > Can one do array of arrays ?

Thanks to all three of you. I used a 4 dimensional array as you suggested. I will have to do a lot of loops with loop variables i and j. I should perhaps save my results from time to time, no ? If I need to save "object1" and "object2", the command should be save(object1,object2,file=paste("save",i,j)), right ? Thank you very much P.S. : It is rather usual to have this kind of work to do, isn't it ? If you have any advice, thanks for telling me. 2008/6/5 Patrick Burns <pburns@pburns.seanet.com>:> I think what you want is a 3 or 4 dimensional array. > S Poetry has a chapter on such things. > > It is also possible to have arrays of arrays, but I don't > think that is what you want. > > > Patrick Burns > patrick@burns-stat.com > +44 (0)20 8525 0696 > http://www.burns-stat.com > (home of S Poetry and "A Guide for the Unwilling S User") > > Michael Prince wrote: > >> Dear R users, >> >> I want to calculate the bias and variance of an estimator for several >> values >> of two parameters a and b. >> >> For example : >> >> b1 b2 >> a1 bias bias >> variance variance >> a2 bias bias >> variance variance >> >> Can one do array of arrays ?
