• ## Linear Equations

2021-12-16 · Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable. If the linear equation has two variables, then it is called linear …

Linear pair. A linear pair is a pair of adjacent angles whose non-adjacent sides form a line.. In the diagram above, ∠ABC and ∠DBC form a linear pair. The angles are adjacent, sharing ray BC, and the non-adjacent rays, BA and BD, lie on line AD.

• ## Understanding t-test for linear regression

2018-5-2 · With linear regression we basically get the same thing. In vector form, β ^ ∼ N ( β, σ 2 ( X T X) − 1). Let S j 2 = ( X T X) j j − 1 and assume the predictors X are non-random. If we knew σ 2 we''d have. β ^ j − 0 σ S j ∼ N ( 0, 1) under the null H 0: β j = 0 so we''d actually have a Z test. But once we estimate σ 2 we end up ...
