Description

The file Model_Sim_data.txt is a tab-delimited text file containing the data used to simulate dose-response, broken-stick, step-function, and linear response models in the evaluation of TITAN-derived change points

Column definitions:

  1. STAID: station identifier
  2. Urb: urban intensity
  3. BS: broken stick model with threshold at 0.5
  4. Lin: linear model with no threshold
  5. STP: step-function model with threshold at 0.5
  6. DR: does-response model with thresholds at 0.35 and 0.65
