 Redundancy is the observation's contribution to the degree of freedom.
 (From 0 to 1 with 1 being best)
 Estimate is used to estimate the blunder which might cause large residuals.
 Marg is a reliability test for a single blunder (Type II error).
 Ext is an external reliability test for an observation
 P = PASS  FAIL = FAIL
