  1. Loglinear model results for MCHD data blocked on last name and first name (Number of record pairs = 618,213). All parameters are statistically significant (p < .001) for all three models, except for u2 which is not significant for conditional independence model (p = .468) or Loglinear Model I (p = .143).
