Finding Leverage/Hatvalue of Influential Observations

WebThe most common formula to calculate a Z score involves the observation (X), the hypothesized mean (μ), and hypothesized standard deviation (σ): Enter any number for Z to calculate the P value from Z score statistics. Entering your Z score as positive or negative will result in the same P value, because this test is two-sided. Web14. For the data in Exercise 13, identify any leverage points using the hat matrix. ... Because H is a projection matrix (projecting y orthogonally onto the subspace spanned by the columns of X), the average hat-value is p/n.
