Hi My name is Sgio

I from Brazil

Who I made Principal Axis Factorin in SAS????

And who I made the KMO???

Thanks!!!

Are you interested in factor analysis in SAS? Virtually all the factor

analytic approaches will require PROC FACTOR. If you are asking

about Principal Factor Analysis, then PROC FACTOR does that too.

What's KMO? I assume you are not asking about KM Objects

or the Knowledge Management Open.

The KMO is Kaiser-Meyer-Olkin!!! Who I made it is SAS???

In Brazil there is one researcher who speaks who Principal Factor

Analysis not is analysis factorial!!!

Sergio,

I presume that by "Who I made it is SAS???" you mean to ask "How do I

obtain it in SAS?"

If that is correct, then take a look at

http://www.utdallas.edu/ ~nkumar/FactorExample.PDF

The KMO, according to that article, is shown in SAS as "Kaiser's Measure

of Sampling Adequacy".

I think he means something else.....I was reading about this as one of hte options in SPSS'

factor analysis program,

Here's a link to what I think he means, but I don't have time right now to figure out how to reply

XXXX@XXXXX.COM yelled:

Maybe Kaiser's measure of sampling adequacy is called KMO in *one*

stat tool, but that is not a common designation. In SAS, using

PROC FACTOR, you would look for the MSA option.

Then what do you want? Straight, uncluttered factor analysis?

Alpha factor analysis? Principal component analysis? Iterated

principal factor analysis? Unweighted least-squares factor analysis?

Maximum likelihood (canonical) factor analysis? Image component

analysis? Harris component analysis? PROC FACTOR can do all

of these, and more. But I don't know which you mean.

I cannot tell if the problem here is language or jargon. By that,

I mean I cannot tell if the problem is our trying to translate between

Spanish and English, if if the problem is in trying to translate

between one set of names for statistical tools, and another set

of names.

Either way, I don't understand why you have to yell. We're a kind

of civil group here.

HTH,

David

The following excerpts I copied from:

http://www.ats.ucla.edu/stat/sas/library/factor_ut.htm

Factor analysis as a generic term includes principal component

analysis. While the two techniques are functionally very similar and

are used for the same purpose (data reduction), they are quite

different in terms of underlying assumptions.

....

There are still other methods of estimating communalities available in

SAS. Interested readers should refer to SAS manual[4]. Some method

should be chosen, because SAS by default sets all prior communalities

to 1.0, which is the same as requesting a principal components

analysis. This default setting has caused misunderstanding among the

novice users who are not aware of the consequence of overlooking the

default settings. Many researchers claim to have conducted a common

factor analysis when actually a principal components analysis was

performed.

Hope this is what you mean,

Gerben

PS Se voce quer, eu posso tentar ajudar voce em portugues (that's what

they speak in Brazil, David) tambem.

Dang. Mea Culpa. Mary (maryidahosas) pointed this out to me also.

I got a glitch in my wetware: I was thinking this post was from Spain,

while the 'joint inclusion probabilities' post wqas from Brazil.

I do know the difference between Portuguese and Spanish, and I really

can find Brazil on a map. :-)

Hello all, I am trying to write a macro that takes in a number and calcualtes the factorial from 1 to n in the ascending order. I have written it and it is executing properly but i need suggestions to achieve it in lesser number of steps. I am a beginner in SAS and so not very good in building proper logic into the code.can number of loops be reduced? any suggestions would be of great help .
