a

Reduced model included zero regular third, zero be, subject-verb agreement with be, zero irregular past (72% of variance explained).

b

Reduced model included zero be, zero regular third, subject-verb agreement with be, zero irregular past (62% of variance explained).

c

Reduced model included zero regular third, zero be, subject-verb agreement with be, overregularization (88% of variance explained).
