Regressive


Definition:

  • (a.) Passing back; returning.
  • (a.) Characterized by retrogression; retrogressive.

Example Sentences:

  • (1) Multiple stored energy levels were randomly tested and the percent successful defibrillation was plotted against the stored energy, and the raw data were fit by logistic regression.
