Estimates for the Points of Intersection of Two Polynomial Regressions
两个多项式回归交点的估计
Let t* denote an unknown abscissa of intersection of two true regression functions μ1(t) and μ2(t). Under normality assumptions with no restraints on t* the maximum likelihood estimator of t* is shown to be the corresponding intersection of the sample regressions. When this estimate exists confidence intervals J can usually be obtained for t* by an application of the Student t-distribution. When t* is restrained to some known interval I, the ML estimate may or may not fall…
