A simulated data frame with 200 observations and 6 variables, designed to
illustrate Classification Tree Analysis with cta_fit.
This is the dataset used in the CTA.exe demonstration program.
Format
A data frame with 200 rows and 6 columns:
- V1
Class label (integer; 1 or 2).
- V2
Ordered attribute (root in MINDENOM = 1 solution).
- V3
Ordered attribute.
- V4
Binary attribute (0/1).
- V5
Ordered attribute.
- V6
Ordered attribute.
Details
The CTA.exe golden output for MINDENOM = 1 selects V2 as root
(cut = 4.5, ESS = 52.63%). MINDENOM = 8 requires mc_iter = 25000
for parity.
Simulated dataset; no real subjects or PHI. Used as the primary
introductory CTA example in the oda package vignettes and in the
CTA.exe demonstration program (CTA_DEMO.pgm).
