On the Basis of Regression Equation P = a

question 72

Multiple Choice

On the basis of regression equation P = a + b × S + e,we can decompose the variability of the dollar value of the asset,VAR(P) ,into two separate components:

• A)Cov(P,S)= b² × VAR(P)+ VAR(S)
• B)VAR(P)= b^{2 ×} VAR(S)+ VAR(e)
• C)Cov(P,S)= b² × Cov(S,P)+ Cov(S,e)
• D)VAR(P)= b² × VAR(S)
