detecting finite mixtures
...fferent types of distributions, multiple subjects (20, say) respond to many items of each type (100 each, say). Each subject generates two distributions, A vs. B. I run the EM algorithm to find the means for the two subdistributions in each. The algorithm finds two means for both, say Am1, Am2, Bm1, Bm2. Since the algorithm is told to find two distributions, even if there's really only one (as hypothesized for B), it seems wrong to test H0: Am1 = Am2 vs. H0: Bm1 = Bm2 - I'd expect both to be rejected. Rather, I want to test H0: Am1 = Bm1 (should differ) vs. H0: Am2 = Bm2 (should b...

Longitudinal Factor Analysis
I have a data set in the format below. I would like to perform a factor analysis on BM1-BM20 as they are 20 biomechanical measurements of the trial (hitting a baseball). However, my observations are not independent and, I assume, I have to account for this. I have consulted the R literature via RSeek and Google (and I have consulted some very knowledgeable colleagues) and cannot find...

Fitting 3 beta distributions
Hi, I want to fit 3 beta distributions to my data which ranges between 0 and 1. What are the functions that I can easily call and specify that 3 beta distributions should be fitted? I have already looked at normalmixEM and fitdistr but they dont seem to be applicable (normalmixEM is only for fitting normal dist and fitdistr will only fit 1 distribution, not 3). Is that right? Also, my data has 26

Mailboxes not showing up in MS Outlook
Sat, 19 Jul 2014 15:03:03 -0400 I am not sure exactly where the problem is here. I am using a sieve script that sorts various incoming messages into their own mailbox. MS Outlook does not show those folders if they are not directly under INBOX. EXAMPLE: drwx------ 31 vmail vmail 1.0K 2014-07-19 14:46:55 EDT ./ drwx------ 3 vmail vmail 512B 2014-07-02 13:52:03 EDT ../ drwx------ 5

NAS and 2 active Samba servers / locking not working
Hi, I have one NAS which I can access via NFS or Samba. This storage is accessed by 2 linux servers with Samba where I re-export the NAS share. This is sort of an active/active loadbalancing cluster. The only thing not working is locking... If a client opens a Word-File via server1 and another opens the same via server2 it won't inform the user that he can only open the file readonly. I was
