13
Definition of Sequential Analysis Sequential
Association (Yules Q index)

• The analysis of sequences or co-occurrences of
  events or behaviors
• Sequential association The observed sequential
  occurrence NE chance level
• Positive observed frequency of sequence gt chance
• Negative observed frequency of sequence lt chance

14
Definition of terms

• Given event the antecedent behavior,
  predictor behavior, proposed causal behavior.
• Target event the consequence, the proposed
  affected behavior.
• Base rate the observed total frequency of a
  particular behavior in an observation session.

15
Analysis Options

• Sequential Event Based

Y Is Given N Not Given
Y Target A B
N Not Target C D
16
Analysis Options

• Sequential Time Based

Y In window N Not in Window
Y Target A B
N Not Target C D
17
Analysis Options
