data(Prostate)

Format

The data frame has the following components:

lcavol

log(cancer volume)

lweight

log(prostate weight)

age

age

lbph

log(benign prostatic hyperplasia amount)

svi

seminal vesicle invasion

lcp

log(capsular penetration)

gleason

Gleason score

pgg45

percentage Gleason scores 4 or 5

lpsa

log(prostate specific antigen)

Examples

# NOT RUN {
data(Prostate)
attach(Prostate)
pairs(Prostate, col = 1+svi, pch = gleason - 5,
      main = paste("Prostate data, n = ", nrow(Prostate)))
detach()

l1c.P <- l1ce(lcavol ~ ., data = Prostate)
coef(l1c.P)[coef(l1c.P) != 0] ## only age, lcp, lpsa (+ intercept)
summary(l1c.P)
# }
