crosspoints: Calculate crosspoints

In optedr: Calculating Optimal and D-Augmented Designs

Description

Given the parameters for D-augmenting a design, this function calculates the crosspoints in the sensitivity function that delimit the candidate points region

Usage

crosspoints(deff, alpha, k, sens, gridlength, tol, xmin, xmax)

Arguments

deff	Minimum efficiency chosen by the user
alpha	Combined weight of the new points
k	Number of unknown parameters of the model
sens	Sensitivity function of the design for the model
gridlength	Number of points in the grid to find the crosspoints
tol	Tolerance that establishes how close two points close to one another are considered the same
xmin	Minimum of the space of the design
xmax	Maximum of the space of the design

Value

A numeric vector of crosspoints that define the candidate points region
