Dear All,
Sorry to bother you again. As my previous mail was messy to understand,
please find it again to give me a solution. I'd like to do a partial
correaltion test ['pcor.test ()' or 'parcor()'] between Irid.area and
Casa.PC1 variables controlling the influence of SL (co-variate) according

Dear all,
I'm writing my manuscript to publish after analysis my final data with
ANOVA, ANCOVA, MANCOVA. In a section of my result, I did correlation of my
data (2 categirical factors with 2 levels: Quantity & Quality; 2 dependent
var: Irid.area & Casa.PC1, and 1 co-var: SL). But as some traits (h
Hi
does anyone know if there is any R function that preforms partial
correlations analysis for censored data?
I found a fortran program on the PSU website at
http://www2.astro.psu.edu/statcodes/cens_tau.f
but I was wondering if there is anything like that in any R package.
Thanks

A good start might be to go to http://rseek.org and search for
partial correlation to get information on the packages and functions
that offer it.
>From there, if you have specific questions, describing your data,
what you've tried, what results you've gotten, and what results
you expect would be
how can I compute partial correlation
there's four variables;
income, age, educational level, race.
income is indenpendent variable
and race is nominal variable
I want to calculate partial correlation or semi-partial correlation between
income & race
help me out... thanks.

Hi all,
This message is in response to:
http://www.mail-archive.com/r-h...@stat.math.ethz.ch/msg93690.html
Basically, in SAS you can retrieve the partial correlation coefficients using:
proc reg data = ch11q02;
model y = x1 x2/pcorr1 pcorr2;
run;
quit;
Is there a comparable way to retrieve
Why do we get Partial correlation values greater than 1?
I have used the default function pcor.mat :--
I have manipulated the default pcor.mat function a bit so ignore tha
variables corr_type,element1_in_no,element2_in_no,P.Please ignore the
“pairwise” section and have a look at athe “listwise ”

not sure which library 'pcor' is in, but why don't you just use the ranks of
the variables and then perform the correlation on the ranks:
x<-sample(1:10,10,rep=T)
y<-x+ sample(1:10,10,rep=T)
cor(x,y)
cor(rank(x),rank(y))

Hej!
I have the following problem:
I would like to do partial correlations on non-parametric data. I checked
"pcor" (Computes the partial correlation between two variables given a set
of other variables) but I do not know how to change to a Spearman Rank
