Published (2009-12-05 22:23:00)
for those who are interested, after testing several GUIs i've came to a conclusion that Rattle is one of the best packages. It might not be as good as R commander or Rkward, but it integrates well with Gnome desktop environment.

Hi guys , Im trying to get a better understanding of this , hope you can take a look at this , my biggest problem is how to interpret FA model in R .

Regression on Binned data
Published (2009-11-30 09:38:00)
Hi, Can I carry out linear regression reliably with binned data. IE. data on cases falling into a series of ranges over time. I can imagine that if the upper bin limit is used to describe the data that an ordinary regression will proabably still estimate the slope, but overestimate the intercept. Are there any methods for this type of data (small example below) Year Bin 2002 1 2002 1 2002 2 2003 1 2003 2 2003 3 2003 3 2003 3 2004 1 2004 3...

T tests using R
Published (2009-11-30 14:44:00)
You should try permutation test in package "coin", but... Do no take seriously a two-side test. Of course, both diets ARE DIFFERENT, it's imposible that diet1= diet2, always there will be a difference, however small it may be, the fact that we don't be able to detect it is another thing. All two-side Statistical Hypothesis are falses! With a small sample you have less probability to find any difference. With a huge...

1 vs 2,3,4,5 1,2 vs 3,4,5 1,2,3 vs 4,5 1,2,3,4 vs 5 this would be, respectively: -1 , 1/4 , 1/4, 1/4, 1/4 -1/2, -1/2, 1/3, 1/3 1/3 -1/3, -1/3, -1/3, 1/2, 1/2 1, -1/4, -1/4 -1/4, -1/4 See Dragan's post for further clarification: http://talkstats.com/showthread.php?t=8093

Hi everyone !! I'm a newby actually, so I hope you'll understand my problem here I have a serie of data (the times spent by a car at a control-station) and it follows a Pearson 5 distribution. I'd like to test it with the khi squared test. (also, it's for a university project and I need to have bins with same probabilities) My main problem is that I don't know what is the Alpha and Beta of the Inverse Gamma...

help with contrast coding
Can someone help me with the following questions. I am really dumb when it comes to this and any answer I give would be purely a guess. It is a question about contrasts in R (although R isn't needed for this bit).
The continuous variable is "depression".
