R: Test Linear Hypothesis - Mathematics

NettetThe hypothesis matrix can be supplied as a numeric matrix (or vector), the rows of which specify linear combinations of the model coefficients, which are tested equal to the corresponding entries in the righ-hand-side vector, which defaults to a vector of zeroes. Alternatively, the hypothesis can be specified symbolically as a character vector ... Nettet9. mai 2016 · Let β ^ be your regression estimates of β. Under the condition that β ^ ∼ N ( β, Σ) conditional on data X (eg. β ^ asymptotically normal with mean β and covariance matrix Σ) then the linear restrictions R β = r can be tested with a χ 2 test. Observe that R β ^ − r would be normal with V a r ( R β ^ − r ∣ X) = R Σ R ′. chevy cruze model years
