Re: [R] Hausman Test

Dear Achim, Sorry to have disturbed you. I have encountered a problem when computing Hausman test statistics (i.e. p values) in R to compare OLS and 2SLS models. The problem is a discrepancy between the two p-value outputs from the "manual approach (by hand)" and the " diagnostics argument"

No you may not. I suggest that you *first search before posting* -- e.g. on "R package moments of distributions" -- where you would find the package "moments" that apparently already does exactly what you suggest (there are some other packages as well). You could also first search the CRAN task

[R] (d,p,r,q) for all distributions, but no m?

Today I need to compute the means for some distributions... and there's no easy way to do it! I mean (no pun intended), there is (d,p,r,q) for all distributions (like: dgamma, pgamma, rgamma, qgamma; dchisq, pchisq, rchisq, dchisp; etc), but there is no "m"-functions, like a mgamma to get the

Re: [R] Where are the PCA outputs?

At the risk of being redundant, the command prcomp(pcl, scale.=T) is the same as the command print(prcomp(pcl, scale.=T)). This passes the results of prcomp() to print() which prints some of them (whatever the function print.prcomp() is programmed to display) and then throws them away. To save

Re: [R] Where are the PCA outputs?

Hi Nick, "prcomp" returns an object of class "prcomp" so when you simply 'print' the object it gets passed to the "print.prcomp" function. If you want to see all the objects you should assign the results to an object. Regards, Charles On Mon, Sep 12, 2016 at 7:56 AM, WRAY NICHOLAS

Hi R Folk I have been kicking some data around and one thing has been to try a PC analysis on it, but whereas in the online examples I've looked at the prcomp function gives a set of five outputs when I use the prcomp function it only gives me a set of standard deviations and the rotation matrix
