Hi,
I have a question regarding the modeling methodology of the following problem:
* I have two data sets {X_i,y_i} {X_i,z_i}, i=1..N,
where y_i = f(X_i) + i.i.d. Gaussian noise
and z_i = g(X_i) + i.i.d. Gaussian noise
* I apply bayesian linear regression to each of them and obtain
p(y|X
Hi, are the methods for multiple testing p value adjustment (Shaffer, Westfall,
free) implemented in the function adjusted() in multcomp package so called
closed testing procedure? what about those methods (holm, hochberg, hommel, BH,
BY) implemented in the p.adjust() in the stats package?

Are you running a script using 'source' or in batch mode? And do you want the
script to get input from a user instead of from the script? If that is the
case then you need to work a little harder because R assumes that if you are

Thanks for any suggestions,

do you know what it is, and what version? (If you do have access to the

I have a bunch of data files all with "dbs" file extensions. They are

It will never hurt your chances to get an answer if you tell what the code in
the different language actually does. Is it doing t-est for all of the
