data1: Simulated dataset 1
In MethodCompare: Bias and Precision Plots

In the simulated dataset 1, each subject has 1 measurement value 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.

data1

An object of class data.frame with 1255 rows and 3 columns.

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 1 was created based on the following equations:

y_1i=-4+1.2*x_i+ε_1i, ε_1i | x_i ~ N(0,1+0.1*x_i)^2)

y_2ij=x_i+ε_2ij, ε_1i | x_i ~ N(0,(2+0.2x_i)^2)

x_i ~ Uniform[10-40]

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