- Consider the following linear regression model, which links the response variable y with k predictor variables x1, x2,..., xk:y=β0+β1x1+β2x2+... +βkxk+ε. If, for example, the slope coefficient β1 equals zero, then the predictor variable x1 does what and implies what? Choose all that answer the 'does what?' and 'Implies what?' questions!-Implying that x1 does not influence y-Drops out of the equation-Then x1 influences y-Does not drop out of the equation
- The nonzero slope coefficient test is used for a renowned financial application referred to as the capital asset pricing model (CAPM).The model y = α + βx + ɛ, is essentially a simple linear regression model that uses α and β, in place of the usual β0 and β1, to represent the intercept and the slope coefficients, respectively. Which of the following is true about the slope coefficient β, called the stock's beta? Select that apply!Multiple select question.-When β equals 0, any change in the market return leads to an identical change in the given stock return.-A stock for which β > 1 is considered more "aggressive" or riskier than the market-Measures how sensitive the stock's return is to changes in the level of the overall market-When β equals 1, any change in the market return leads to an identical change in the given stock return.
