similar to: FIML in lme

Does anyone know if someone is developing full-information maximum likelihood (FIML) estimation algorithms for basic regression functions, like glm()? I think that having FIML options for workhorse functions that typically use ML would give R an edge over other statistical software, given how well FIML performs in missing data situations compared to ML. While my current level of programming

Is there a way to use full information maximum likelihood (FIML) to estimate missing data in the sem package? For example, suppose I have a dataset with complete information on X1-X3, but missing data (MAR) on X4. Is there a way to use FIML in this case? I know lavaan and openmx allow you to do it, but I couldn't find anything in the documentation for the sem package. Thanks! -- Dustin Fife

I have been working through the book "Applied longitudinal data analysis: modeling change and event occurrence" by Judith D. Singer and John B. Willett. I have been working examples using SAS and also using it as an opportunity for learning to use R for statistical analysis. I ran into some difficulties in chapter 8 which deals with using structural equation modeling. I have tried to

Hello! I am trying to reproduce (for a publication) analyses that I ran several months ago using lavaan, I'm not sure which version, probably 0.4-12. A sample model is given below: pathmod='mh30days.log.w2 ~ mh30days.log + joingroup + leavegroup + alwaysgroup + grp.partic.w2 + black + age + bivoc + moved.conf + local.noretired + retired + ds + ministrytime + hrswork + nomoralescore.c +

Hi I want to set up * as a conference bridge. I would like to be able to conference is SIP calls (up to 12) I am looking through all available documentation for * to get info on how it is done. No luck so far. Can somebody direct me to the info in this subject?

I am fitting individual growth models using nlme (multilevel models with repeated measurements nested within the individual), and I am trying to calculate the Pseudo R-squared for the models (an overall summary of the total outcome variability explained). Singer and Willett (2003) recommend calculating Pseudo R-squared in multilevel modeling by squaring the sample correlation between observed and

I have a STRUTS based webapp and I want to port it to RUBY/RAILS... Can anyone suggest a migration strategy...I would like to migrate my struts actions over time if possible.

I am trying to model data in which subjects are followed through time to determine if they fall, or do not fall. Some of the subjects fall once, some fall several times. Follow-up time varies from subject to subject. I know how to model time to the first fall (e.g. Cox Proportional Hazards, Kaplan-Meir analyses, etc.) but I am not sure how I can model the data if I include the data for those

Hello , I saw that in open source projects which use speex , like sweep and linphone , (there are links in speex website to these projects) the encoding/decoding process is done using vorbis/ogg. (The encoded files which are produced has , for example, "ogg" header). Is there anywhere examples using speex library for encoding and decoding raw files with no "ogg" header?

Is it possible to replace the word "R Console" on the title bar (is it what it's called? It's the blue area above menu bar) with the name of the work space file you're using or loaded, so people who are runing multple R sessions at same time can identify them immediately. I'm using 1.9.0 in SDI mode. Thanks, ...Tao

Hi All, I know, IAX is NAT friendly, but... I have a problem running gnophone from a box behind NAT firewall. I can register gnophone with * through NAT, but when I try to make a call it instantly disconnects. CLI iax show peers command tells me that peer is unreachable. However this peer is registred. Gnophone also tells me that it is registred. It seems that registration handshake has

Hello, I am new to Linux, Samba, and actually servers in general. I am attempting to set up a Linux file server and join it to a Windows 2000 domain. All I want to be able to do is get files from the linux file server and put files on it. I do not want it to be the domain controller. I join the domain using: net join -S 10.10.10.40 -UAdministrator%password It tells me that I have joined

I just can't find the answer to solve this issue and I thought someone would know the answer. Finally got SWAT running and configuring a clean smb.conf file.
