EXAM PREPS
The human resources manager of a certain company is concerned about the level of employee
absenteeism. He identified three factors which he believes are the most significant contributors to
employee absenteeism at the company:
x = the length of job tenure of an employee (measured in months)
xɔ = the level of job satisfaction (measured by an index from 0 to 75)
x3 = the level of an employee's commitment (measured by an index from 0 to 70)
random
sample
of
20
employee
records
selected
and
the
model
was
E(v) = Bo +B + Bx2 + Bzx3 was fitted to the sample data. The results are given in the SAS
printout on page
7.
Using the values of the standardized residuals on the printout how to I identify any outliers.
