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

question 78

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:

Definitions:

Atom Model

A representation or theory that describes the structure and behavior of atoms, the basic unit of matter. The most widely known example is the Bohr model, with electrons orbiting a nucleus.

Electrons

Electrons are subatomic particles with a negative electric charge, found in all atoms, and play a crucial role in chemical reactions and electricity.

Orbital Paths

Paths in space along which objects such as planets, moons, and satellites travel around another body.

Electron Shells

Electron shells are layers of electrons that surround the nucleus of an atom, where each shell has a different energy level.
