[R] score test statistic in logistic regression

2008-02-27 Thread bkelcey
Hi, looking for a function or syntax to estimate the score test in logistic regression for the null hypothesis b1=0 in the model logit(p)=b0+ b1*x +b2*z. Data comes from the binomial distribution (n,p). Thanks, ben __ R-help@r-project.org mailing

[R] generate fourth vector based on known correlations

2007-09-27 Thread bkelcey
I am trying to generate a fourth vector,z, given three known and fixed vectors, x1,x2,x3with corresponding known and fixed correlations with themeselves and with z. That is, all correlations are known and prespecified. How can I do this? Thank you, ben
