TABLE 15-6 Given Below Are Results from the Regression Analysis on 40

question 30

True/False

TABLE 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 (X₁), the number of years of education received (X₂), the number of years at the previous job (X₃), a dummy variable for marital status (X₄: 1 = married, 0 = otherwise), a dummy variable for head of household (X₅: 1 = yes, 0 = no) and a dummy variable for management position (X₆: 1 = yes, 0 = no).
The coefficient of multiple determination (R) for the regression model using each of the 6 variables Xⱼ 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 Table 15-6, there is reason to suspect collinearity between some pairs of predictors based on the values of the variance inflationary factor.

Definitions:

Normal Distribution

Firm

A business organization, such as a company or partnership, engaged in commercial, industrial, or professional activities.

Organization

Poisson Probability Distribution

Describes the probability of a given number of events happening in a fixed interval of time or space when these events occur with a known constant mean rate.
