crossReg-package:
Confidence intervals for crossover points
Description
Given the linear regression model y = b0 + b1*x1 + b2*x2 + b3*x1*x2, the crossover point of the two simple regression lines implied by the linear regression model can be expressed as C = -b2/b3 (Aiken and West, 1991). This package provides functions to calculate confidence intervals for crossover points of two simple linear regression lines using
the non-linear regression, the delta method, the Fieller method, and the bootstrap methods.
