Question

Multiple regression analysis was performed on a set of data containing 5 independent X1, X2, X3, X4, and X5. No signs of collinearity exist among the variables. The p-values corresponding to the coefficients of X1, X2, X3, X4, and X5 are 0.0001,0.5011,0.0013,02401, and 0.1 892, respectively. Let Bl , B2, B3, B4, and B5 be the coefficients of the independent variables X1, X2, X3, X4, and X5, respectively. Write a multiple regression model for the data using only the significant independent variables in the model. (Use B0 as the constant.)

Explanation / Answer

Ans:

From above given p-values only X1 and X3 are significant,as p-values are very very small.

So,

Multiple regression model:

Y'=B0+B1X1+B3X3
