WebThe phrase "linear equation" takes its origin in this correspondence between lines and equations: a linear equation in two variables is an equation whose solutions form a line. If b ≠ 0, the line is the graph of the function of x that has been defined in the preceding section. If b = 0, the line is a vertical line (that is a line parallel to ... Web5 okt. 2024 · To examine parallelism of the two regression lines, we used the z -test [ 10 ]: z=\frac {\left {\beta}_1- {\beta}_j\right } {\sqrt {\sigma {\left ( {\beta}_1\right)}^2+\sigma {\left ( {\beta}_j\right)}^2}}. (26) If the absolute z -value exceeded 1.96, the two regressions were non-parallel; otherwise, they were parallel. Case studies
