ZelazoKolb1972

The Zelazo, Zelazo and Kolb (1972) dataset consists of ages (in months) at which 
an infant starts to walk alone from four different treatment groups (Active-exercise, 
Passive-exercise, 8 week Control, No-exercise).

Allow for easy-to-use testing or evaluating of linear equality and inequality restrictions about parameters and effects in (generalized) linear statistical models.
