The Population Multiple Regression Model When There Are Two Regressors,X1i

question 47

Multiple Choice

The population multiple regression model when there are two regressors,X1i and X2i can be written as follows,with the exception of:

• A)Yi = β0 + β1X1i + β2X2i + ui,i = 1,... ,n
• B)Yi = β0X0i + β1X1i + β2X2i + ui,X0i = 1,i = 1,... ,n
• C)Yi = Xji + ui,i = 1,... ,n
• D)Yi = β0 + β1X1i + β2X2i + ...+ βkXki + ui,i = 1,... ,n

Definitions:

Demand Characteristics

Demand Characteristics refer to subtle cues or signals in an experimental setting that influence the participants' behavior or responses, potentially skewing the study's results.

Correlation

A quantitative measure demonstrating how closely two or more variables vary together.

Causation

The action of causing something, indicating a relationship between two events where one is the result of the other.

Third-variable Problem

The third-variable problem occurs when a previously unconsidered variable affects both variables of interest, potentially falsely suggesting a causal relationship between them.
