SCENARIO 15-6 Given below are results from the regression analysis on 40 observations where the dependent variable is the number of weeks a worker is unemployed due to a layoff (Y)and the independent variables are the age of the worker ( ), the number of years of education received (
), the number of years at the previous job (
), a dummy variable for marital status (
1 = married, 0 = otherwise), a dummy variable for head of household (
1 = yes, 0 = no)and a dummy variable for management position (
1 = yes, 0 = no). The coefficient of multiple determination (
)for the regression model using each of the 6 variables
as the dependent variable and all other X variables as independent variables are, respectively, 0.2628, 0.1240, 0.2404, 0.3510, 0.3342 and 0.0993. The partial results from best-subset regression are given below:
-Referring to Scenario 15-6, the variable X6 should be dropped to remove collinearity?
Glutamate
A major excitatory neurotransmitter in the nervous system involved in memory, learning, and brain development.
Adrenal Gland
A gland above the kidney that produces hormones such as adrenaline and cortisol, which help control heart rate, blood pressure, and other important bodily functions.
Cortisol
A steroid hormone released by the adrenal glands in response to stress or low blood-glucose concentration.
