data3: Simulated dataset 3

Description Usage Format Details

Description

In the simulated dataset 3, 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 3 and proportional bias of 0.9. Variance of the new method is larger than that for the referene method.

Usage

1

Format

An object of class data.frame with 1250 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 3 was created based on the following equations:

y_1ij=3+0.9*x_i+ε_1ij,ε_1ij|x_i~N(0,2+0.06*x_i)^2)

y_2ij=x_i+ε_2ij,ε_1i|x_i~N(0,(1+0.01x_i)^2)

x_i~Uniform[10-40]

for i = 1, 2, …, 100, j=1,2,…,n_1i or n_2i and the number of repeated measurements for each subject i from the new and reference method was n_1i ~ Uniform[1-5] and n_2i ~ Uniform[10-15] respectively.
