Hola, Todos estamos muy bien, gracias. Con respecto de tu consulta, creo que ofreces poca información para poder reproducir o intentar emular tu inquietud (aunque en este grupo de voluntarios hay gente muy hábil que seguramente podrá ayudarte mejor). Yo me pregunto, por ejemplo: ¿cómo son tus datos originalmente?¿los estás leyendo de otro programa?¿los tienes en un texto plano?¿podrías enviar

¿existe algún método en el cual no sea necesario hacer este trabajo y que aparezcan los nombres de las preguntas? label.cronbach <- label.var(p01, "¿Le agrada el programa que se le ha mostrado? ") label.cronbach <- label.var(p02, "¿Cree que ayuda en el aprendizaje?") label.cronbach <- label.var(p03, "¿Propicia el trabajo en el equipo?") label.cronbach

Estimado José, Es la segunda vez que veo te pregunta en este Foro, la primera vez se te pidió mas detalles y luego se te dio una respuesta. El hecho que reiteres tu pregunta, sin detalles y sin mencionar que es lo que no funcionó con la respuesta anterior, me hace recordar algunas recomendaciones que leí en una excelente respuesta en http://stackoverflow.com/, que trato de adaptar a

Dear all, i need help about comparing 2 alpha cronbach. How to derive W statistic. Are alpha cronbach and Hoyt's method using ANOVA identical? Thank you for your help. Regards --------------------------------- Luggage? GPS? Comic books? [[alternative HTML version deleted]]

Yeah:) I''d like to work on this. Here are my first observations: - We need to call vdev_op_asize method with additonal ''offset'' argument, - We need to move data to new disk starting from the very begining, so we can''t reuse scrub/resilver code which does tree-walk through the data. Below you can see how I imagine to extend RAIDZ. Here is the legend:

Dear R users. Recently I wanted to update my R distribution to the current one (R-2.7.1). I am running a Fedora core 8 distirbution. The installation went fine, but when I tried to add some additional packages the majority made an exit with an error. Only a few least demanding (e.g. RColorBrewer) managed to get through the installation process. What happened between the versions 2.6.x and 2.7.x

Dear all, I was wandering what could be wrong with my system (regularly updated Fedora core 8) so that installing packages does not succeed with almost every package. I follow the procedure specified in the help file R-admin section 6.3. This is not a feature new to the current version but happened (to me) in the previous version as well. Additionally R-help html pages try to follow wrong links

Dear Listers: I used cronbach{psy} to evaluate the internal consistency and some set of variables gave me alpha=-1.1003, while other, alpha=-0.2; alpha=0.89; and so on. I am interested in knowing how to interpret 1. negative value 2. negative value less than -1. I also want to re-mention my previous question about how to evaluate the consistency of a set of variables and about the total

hie 1...i'm trying to carryout a relibility testusing cronbach's alpha what fuctin do i use. 2.. this is more of a statistical question.if the alpha value for all the variables is negative what does it mean. and if the alpha value is negative for all tyha variables but is greater than 0.7 for some sections of the variables what does that mean thanks in advance

Hi list members Any easy way to get standardized cronbach's alpha for a scale, as in SPSS?

Hello, I was reading your posts about RSYNC. We have a massive Oracle schema lots of datafiles about 750 GB size. We do rsync datafiles from source to target server but everytime we cleanup the datafiles on the target server and do rsync every 2 weeks. On the target side mostly the datafiles will be same but on source we might have added few datafiles or made some changes in data and as such the

I need to rsync 4 TB datafiles to remote server and clone to a new oracle database..I have about 40 drives that contains this 4 TB data. I would like to do rsync from a directory level by using --files-from=FILE option. But the problem is what will happen if the network connection fails the whole rsync will fail right. rsync -a srchost:/ / --files-from=dbf-list and dbf-list would contain this:

Hi All, I would to rsync data spread of many files from remote site. Each file may exist in total different location - the path for each file may be different. My question is: Can I do it one single rsync command, giving a file containing list of paths as parameter, or do I need to run rsync for each file. I did not find any option doing it in the man page. I tried to play with

Hi all, I am trying to teach myself to use and program R (How else do you do it? lol) Anyway, I wrote a piece of code to compute coefficent alpha for a scale. As I am neither a statistician nor a programmer, I wanted people's feedback. The code appears to work (Win 95 with R 1.0.1) and I have verified my result with SPSS and it was correct (much to my astonishment!). Nonetheless, I am

Hello, I have written a small function ('JostD' based upon a recent molecular ecology paper) to calculate genetic distance between populations (columns in my data set). As I have it now I have to tell it which 2 columns to use (X, Y). I would like it to automatically calculate 'JostD' for all combinations of columns, perhaps returning a matrix of distances. Thanks for any help
