siRSM (version 1.1)

ci.surface: Conditional Inference of Response Surface

Description

Computes 95% bootstrap confidence intervals for various features of the quadratic response surface, CONDITIONAL on the single index.

Usage

ci.surface(obj, B=500, use.parallel=TRUE)

Arguments

obj

an object of class siRSM, typically result from siRSM

B

number of bootstrap samples

use.parallel

if TRUE, exploits multiple cores by using foreach, doSNOW, etc

Value

stationary.point

stationary point, (u0, v0)

prin.ax.1

1st principal axis, intercept (p10) and slope (p11)

prin.ax.2

2nd principal axis, intercept (p20) and slope (p21)

beta

coefficients defining the quadratic response surface, b0, b1, ..., b5

line.congr

slope (ax) and curvature (ax2) along the congruence line, u-v=0

line.incongr

slope (ax) and curvature (ax2) along the congruence line, u+v=0
