The Akaike information criterion (AIC) is an estimator of the relative quality of statistical models for a given set of data.

Question No: 10 Correct Answer Marks: 1/1 In a simple linear regression model (One independent variable), If we change the input variable by 1 unit. How much output variable will change? For linear regression we know that Y=a+bx+error. And if we neglect error then the equation is Y=a+bx. Therefore, if x increases by 1, then Y = a+b(x+1) which implies Y=a+bx+b. So Y increases by its slope. change by 1 unit no change by intercept by its slope You Selected Previous Next
