In the data set shown below, CONTRIBis the variable indicating contribution to the plan in dollars at the end of its first year. SUSAN is a categorical variable taking on the value of 1 if Susan Shepard sold the policy and 0 if she did not. GROUP takes on the value of I if the client also has a group life or group health insurance policy with Best Retirement; if not, GROUP is 0. TURNOVER is the employee turnover rate. It mea- sures the percentage of employees terminating employment each year. ESTIMATE is the estimated end-of-year contributions in dollars and SALARY is the average annual employee salary in dollars. ELIGIBLE is the number of employees eligible to partici- pate in the 401(k) plan. VEST and FAILSAFE are both binary variables: does the plan have immediate vesting of employer contributions (0 = no, 1 = yes) and does the plan have a fail-safe provision (0 = no, 1 = yes)? MATCH is the percentage of the contri- butions matched by the employer. Can you do better than the underwriter at estimating year-end contributions?
