Missing Values
An observation read from a DATA= or HISTORY= data set
is not analyzed if the value of the subgroup variable
is missing.
For a particular process variable, an observation read from a
DATA= data set is not analyzed if the value of the process
variable is missing.
Missing values of process variables generally lead to unequal
subgroup sample sizes.
For a particular process variable, an observation read from a
HISTORY= data set is not analyzed if the values
of any of the corresponding summary variables are missing.
