## Variable

An element in a model. For example, in the model RS&Pt+1 = a + b Tbill t + et, where RS&Pt+1 is the return on the S&P in month t+1 and Tbill is the Tbill return at month t, both RS&P and Tbill are "variables" because they change through time; i.e., they are not constant.

## Variable

Anything that does not have a set value. In basic algebra, a variable is often expressed as "x." Variables in economics and finance may be measures such as GDP, prices, or interest rates. Analysts use complicated equations to determine the value of some variables at the present time and even more complicated equations to predict their possible future values. See also: Regression.

To check the robustness of my results, I estimated prediction equations using real disposable personal income instead of labor income as one of the control variables. The findings were almost identical to those using labor income.
The association of referral source with the control variables indicates the need to adjust for the influence of demographics and job quality (indexed by employee income) when estimating the influence of referral source on the dependent measures as the control variables provide estimates of different labor markets.
Many control variables (e.g., stolen bases the preceding year of arbitration) showed whites having an advantage.
