Divide the oldest children in the family lung function data set into two groups based on weight:

less than or equal to 101 versus greater than 101. Perform a stepwise discriminant function analysis using the variables OCHEIGHT, OCAGE, MHEIGHT, MWEIGHT, FHEIGHT, and FWEIGHT. Now temporarily remove from the data set all observations with OCWEIGHT between 87 and 115 inclusive. Repeat the analysis and compare the results.
