  ANSWER KEY for both sides of the model

DATA:
  FILE = MPLUS_Chapter5.csv;
  FORMAT = FREE;

DATA LONGTOWIDE:
  LONG = outcome;
  WIDE = outcome1-outcome4;
  IDVARIABLE = PersonID;
  REPETITION = wave (1-4);

DEFINE:
  time = wave - 1;

VARIABLE:
  NAMES = PersonID wave outcome;
  USEVARIABLES = outcome1-outcome4;
  MISSING = ALL (-9999);

ANALYSIS:
  ESTIMATOR = ML;
