| Salary |
Actual salary (in dollars) used; Data retrieved from the
City University Personnel System (CUPS) database by Gowrie
Kaminsky in Hunter College's Department of Human Resources
on 1 December 2004. RRI and supplemental salaries were not
included in these analyses.

| Sex |
Female = 1

| Years since degree |
2004 – year of final degree reported on CUPS database;
CUPS data retrieved by Gowrie Kaminsky in Hunter College's
Department of Human Resources on 1 December 2004
|
| Years since degree (centered) |
To reduce redundancy, this variable was centered by subtracting
the mean of the variable from each of the measures of the variable.
(YsD - meanYsD)
|
| Time in current rank (rank as of 1 December 2004) |
Number of years in current appointment |
| Time in current rank (Centered ) |
To reduce redundancy, this variable was centered by subtracting
the mean of the variable from each of the measures of the variable.
(TIR - meanTIR)
|
| Sum TiR (Total length of employment at HC) |
Time at Hunter College takes into account all tenure-line
years worked at Hunter College for each professor as of 30
June 2004; CUPS data retrieved by Gowrie Kaminsky in Hunter
College's Department of Human Resources on 1 December 2004
|
| Sum TiR (Total length of employment at HC) -- Centered |
To reduce redundancy, this variable was centered by subtracting
the mean of the variable from each of the measures of the variable.
(Sum - meanSum) |
| Rank |
Distinguished Professor = 1; Professor = 1; Associate Professor
= 1
|
| Department |
Departments were grouped into broader discipline categories
(natural and social sciences) instead of using individual departments
to ensure that a sufficient number of faculty fell into each
category (discipline and rank); Natural Science = 1 |
Note: The regression output was generated by SPSS 11.5
Example 1: To
predict the salary of a male assistant professor in the social
sciences who
has had his degree for 5 years and has
been in that rank for 2 years, look first at the constant term,
$71295.48, listed in the first row in the Coefficients table
on the first sheet, "Salary
a". Since the dummy variables were chosen as they were, the constant
represents the salary for a male assistant professor in the social
sciences. Multiply 5 (Years since degree) by 787.27 and 2 (Time
in current rank) by -147.04. Add these totals to the constant to
get a more accurate estimate of salary. The outcome using these
unstandardized regression coefficients is $74937.75.
Example 2: To
predict the salary of a male assistant professor in the social
sciences who
has had his degree for 5 years and has
been at Hunter College for 2 years, look first at the constant
term, $70887.99, listed in the first row in the Coefficients
table on the
second sheet, "Salary b". Since the dummy variables were
chosen as they were, the constant represents the salary for a male
assistant professor in the social sciences. Multiply 5 (Years since
degree) by 863.55 and 2 (Time at Hunter College in years) by -195.63.
Add these totals to the constant to get a more accurate estimate
of salary. The outcome using these unstandardized regression coefficients
is $74814.48.
