Take a moment of Re f lexion. ..... A. Which of the following is NOT true? 1. the point Xbar, Ybar always lies on the regression line e um of the residuals is always zero 2. the sum of the residuals is always zero 3. the mean of the fitted values of Y is the same as the observed values of Y 4. there are always as many points above the fitted line as there are below it 5. The regression line minimises the sum of the squared residuals B. The least squares etimator of the slope coeficient is nbiased means unbiased means 1. the estimated slope coefficient will always be equal to the true parameter value

Unformatted text preview: 2. the estimated slope coefficient will get closer to the true parameter value as the size of the sample increases 3. the estimated slope coefficient will be equal to the true parameter if the sample is large 4. the mean of the sampling distribution of the slope parameter is zero 5. if repeated samples of the same size are taken, on average their value will be equal to the true parameter ie_Slides02 R.
