Description

Data from a study by by Stamey et al. (1989) to examine the association between prostate specific antigen (PSA) and several clinical measures that are potentially associated with PSA in men who were about to receive a radical prostatectomy. The variables are as follows:

• X: A design matrix with 97 instances (rows) and 8 predictor variables (columns). The columns are:

  • lcavol: Log cancer volume

  • lweight: Log prostate weight

  • age: The man's age

  • lbph: Log of the amount of benign hyperplasia

  • svi: Seminal vesicle invasion; 1=Yes, 0=No

  • lcp: Log of capsular penetration

  • gleason: Gleason score

  • pgg45: Percent of Gleason scores 4 or 5

• y: Log PSA
