  # prepare data
  DATA <- subset(ZelazoKolb1972, Group != "Control")
  
  # fit unrestricted linear model
  fit.lm <- lm(Age ~ -1 + Group, data = DATA)
  
  # restricted linear model with restrictions that the walking 
  # exercises would not have a negative effect of increasing the 
  # mean age at which a child starts to walk.
