data2 {MethodCompare}

Simulated dataset 2

Description

In the simulated dataset 2, each subject has 1 to 5 measurement values from the new method and 10 to 15 measurement values from the reference method. Compared to the reference method, the new method has differential bias of -4 and proportional bias of 1.2. Variance of the new method is smaller than that for the reference method.

Usage

data2

Format

An object of class data.frame with 1239 rows and 3 columns.

Details

@format A data frame with three variables:

id

identification number for subjects

y1

values from the new measurement method

y2

values from the reference measurement method

Dataset 2 was created based on the following equations:

y_{1ij}=-4+1.2x_{i}+\varepsilon_{1ij}, \varepsilon_{1ij} \mid x_i \sim N(0,(1+0.1x_i)^2)

y_{2ij}=x_i+\varepsilon_{2ij},\varepsilon_{2ij} \mid x_i\sim N(0,(2+0.2x_i)^2)

x_i\sim Uniform[10-40]

for i = 1, 2, \ldots, 100, j=1,2,\ldots,n_{1i} / n_{2i} and the number of repeated measurements for each subject i from the new and reference method was n_{1i} \sim Uniform[1-5] and n_{2i} \sim Uniform[10-15] respectively.
