VAS: Algorithms for Visual Analogue Scales

Description

Algorithms for VAS. The algorithms are applicable to other numerical variables with measurement errors as well.

Usage

VAS.ecdf(x,w,alpha=0.05)

Value

Estimate of the emprical distribution function.

x

grid points

y

ECDF value Fn(x)

lb,ub

lower and upper confidence bands of ECDF.

alpha

significance level

data

raw data

ecdf

Draw ECDF if TRUE.

Arguments

x

Raw data

w

weights

alpha

Significance level for confidence bands.

Examples

 x <- rnorm(100, -2.6, 3.1)
