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

question 80

Short Answer

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, what is the value of the Mallow's Cp statistic for the model that includes X₁, X₅ and X₆?

Definitions:

Construct Validity

Construct validity is demonstrated when the measures of one concept or construct agree with the measures of other related concepts.

"Real-World" Outcomes

describe the actual results or impacts of interventions, policies, or research findings in natural, uncontrolled environments.

Reliability

The consistency of a measurement, test, or research findings across different occasions and contexts.

Validity

The extent to which a test, measurement, or research study accurately reflects or assesses the concept it is intended to measure.
