hi people, I am a newbie to R and I would appreciate it very much if someone can help me. I am used to use SPSS so I don?t have experience with writing a script. I have a questionnaire (questions 1-12) and I would like to use the omega reliability. Question 1-8 is factor 1 and question 9-12 factor 2. How can I write the scripit? Can someone help me??? Thanks in advance Asterios

Dear all I wonder if someone can explain what is the main difference between omega and alpha reliabilities? I understand an omega reliability is based on hierarchical factor model as shown in this graph<http://rgm2.lab.nig.ac.jp/RGM_results/psych:omega.graph/omega.graph_002_big.png>, and alpha uses average inter-item correlations. 1. What I don't understand is, in what condition,

I have a quick statistical question and hoped somebody has a tip for me without me having to go to the local statistician on Monday. I assess 4 statements from 90 subjects. Each of the 4 statements receives one of three responses (say -1, 0, or 1). I can use Cramer's V or Spearman correlations to assess the correlation between each pair of statements, but I am looking for a measure of

Hi there, I checked google for aov. usually one uses summary to see whether the p-value is small. but I want to put aov in my script. how can I get the p-value, (0.1115, 0.6665, 0.6665 in the following example)? thanks YU > datafilename="http://personality-project.org/r/datasets/R.appendix2.data" > data.example2=read.table(datafilename,header=T) > aov.ex2 =

Hello, I'm new to R and have been following many guides including the two-way anova (http://www.personality-project.org/r/r.anova.html). Using that walkthrough including the supplied data I do str(data.ex2) and receive the appropriate types of data as follows: > str(data.ex2) 'data.frame': 16 obs. of 4 variables: $ Observation: int 1 2 3 4 5 6 7 8 9 10 ... $ Gender :

From the documentation I've read, omega can read from multiple databases, but I'm not sure how to go about this. I have three databases created using omindex, currently located at /var/lib/xapian-omega/data/share, /var/lib/xapian-omega/data/users, and /var/lib/xapiax-omega/data/management The quickstart guide says that in omega.conf database_dir should point to the directory

Hello, There is a build error by what looks to be a typo in xapian-applications/omega/omega.cc My checkout is about 15 minutes old, so it's possible it has been caught since then. omega.cc: In function ?int main(int, char**)?: omega.cc:204: error: ?pretty_tery? was not declared in this scope make[3]: *** [omega.o] Error 1 make[3]: Leaving directory

Hi, all: I check out the trunk code from svn yesterday *svn co svn://svn.xapian.org/xapian/trunk xapian* compile process: *./bootstrap* *mkdir build* *cd build* *../configure --disable-documentation* *make* then the error occur: cd xapian-applications/omega && make all make[1]: Entering directory `/home/white127/xapian-svn/build/xapian-applications/omega' /usr/bin/perl

Hello :-) Sorry if this question is na?ve and confused; I'm new to Apache configuration. Can Apache be configured to run omega via a file in the conf.d directory rather than a virtual server? I have been using a virtual server on port 80 but now need to run nagios on port 80 too and do not want to ask the users to start using a URL with a non-standard port for omega. KISS. AFAIK omega

Hi, I have been able to install xapian build index and perform search using php-bindings. Now, I would like to use xapian-omega for indexing and search. There's very few documentation about it.

Hello friends, I have installed xapian-omega for my system installed from Official Debian GNU/Linux Live 11.6.0 lxde 2022-12-17T11:46, It is an old edition but I am okay with it, I tasted the power of xapian while using recoll. I read that xapian is a powerful database building package for character strings, and indexes a directory of files really well. I want to use xapian-omega as a customisable

Dear all, I am a newbie to Xapian-Omega. I installed Xapian-Omega (1.2.14) a few days ago on my freebsd NAS server, and intend to use it to search my CIFS/SMB share. So far it works fine (I am able to search my share using the omega web interface), nevertheless I have few newbie questions. Hoping that somebody can answer my (hopefully not to silly) newbie questions. Indexing file names:

Are there any options to forming queries with Omega? For instance can you specify a proximity search like "file near 5 manager"? If so, where might I find this documented? I don't see it in the docs directory. Thanks Jim.

Folks, Is it possible to query a document value (doc.set_value(i, val)) as part of the Omega query. I know how to do it from code. Is there a query markup to use for Omega? ...Thanks, ...Ken

Hi, I've tested omega (cgi) on several sql databases on my local machine in which runs Ubuntu, using the version 0.9.4 (installed using apt), and I was really satisfied for the results I obtained. I customized a bit the "query" template. But once I installed omega on the server (using apt for Debian, and omega version 0.9.5), I discovered that the relevances didn't work, as
