A regression model between sales (y in $1000) , unit price (x₁ in dollars) , and television advertisement (x₂ in dollars) resulted in the following function: $\hat { y }$ = 7 - 3x₁ + 5x₂

For this model, SSR = 3500, SSE = 1500, and the sample size is 18.The multiple coefficient of determination for this problem is?

Question

A regression model between sales (y in $1000) , unit price (x₁ in dollars) , and television advertisement (x₂ in dollars) resulted in the following function:

\hat { y }

= 7 - 3x₁ + 5x₂

For this model, SSR = 3500, SSE = 1500, and the sample size is 18.The multiple coefficient of determination for this problem is?

Quizplus · Accepted Answer

The multiple coefficient of determination, R², is calculated as SSR / (SSR + SSE) = 3500 / (3500 + 1500) = 0.7000.
