The Population Multiple Regression Model When There Are Two Regressors $X _ { 1 i } \text { and } X _ { 2 i }$

question 5

Multiple Choice

The population multiple regression model when there are two regressors, $X _ { 1 i } \text { and } X _ { 2 i }$ can be written as follows, with the exception of:

• A) \(Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X _ { u } + \beta _ { 2 } X _ { y _ { i } } + u _ { i } , i = 1 , \ldots , n\)
• B) \(Y _ { i } = \beta _ { 0 } X _ { 0 i } + \beta _ { 1 } X _ { 1 i } + \beta _ { 2 } X _ { 2 i } + u _ { i } , X _ { 0 i } = 1 , i = 1 , \ldots , n\)
• C) \(Y _ { i } = \sum _ { j = 0 } ^ { 2 } \beta _ { j } X _ { j i } + u _ { i } , i = 1 , \ldots , n\)
• D) \(Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X _ { 1 i } + \beta _ { 2 } X _ { 2 i } + \ldots + \beta _ { k } X _ { k i } + u _ { i } , i = 1 , \ldots , n\)

Definitions:

Fixed Interval

A schedule of reinforcement where the first response is rewarded only after a specified amount of time has elapsed, leading to a pattern of responses.

Variable Interval

Variable interval refers to a type of reinforcement schedule in operant conditioning where a response is rewarded after an unpredictable amount of time has passed, leading to a steady and resistant response rate.

Variable Ratio

A schedule of reinforcement where a response is reinforced after an unpredictable number of responses, making it highly resistant to extinction.

Fixed Interval

A reinforcement schedule where a reward is given after a predetermined time period has passed following a response.
