This question seems to be weird at first glance but I think this is the appropriate place to ask.
I'm studying Prostate data by Stamey et. al., (1989), data to examine the correlation between the level of prostate-specific antigen and a number of clinical measures in men who were about to receive a radical prostatectomy.
lcavol: log cancer volume lweight: log prostate weight age: in years lbph: log of the amount of benign prostatic hyperplasia svi: seminal vesicle invasion lcp: log of capsular penetration gleason: a numeric vector pgg45: percent of Gleason score 4 or 5 lpsa: response
I wonder if there is a numerical medical information about these variables. For example, “Is there a numerical relationship between
log cancer volume and
log prostate weight?”,
OR, for instance, Can someone say something like “We expect that
seminal vesicle invasion is double amount of
log prostate weight”?
