In ikoenemund/blandxtr: Advanced Bland Altman analysis for method comparison

Description

ci_loa_mover returns confidence intervals (CI) for limits of agreement (LoA) based on MOVER-method (Methods of Variance Estimates Recovery) proposed by Zou (2013).

Usage

ci_loa_mover(n, n_obs, lambda_mod, output_subjects, mssi_mod, wsv,
  var_d_mod, loa_l, loa_u, alpha, beta)

Arguments

n	number of subjects
n_obs	number of observations
lambda_mod	helper variable for calculation of modified between-subjects variance, see Olofsen et al. 2015
output_subjects	data.table containing subject ID and number of measurements of each subject (m_i)
mssi_mod	mssi (modified calculation)
wsv	within-subject variance (unmodified)
var_d_mod	modified variance of mean of all differences
loa_l	lower limit of agreement
loa_u	upper limit of agreement
alpha	for 100*(1-alpha)%-confidence interval around LoA
beta	for 100*(1-beta)%-confidence interval around bias

Value

A list with the following elements is returned

• ci_l_loa_l_mover lower limit of 95%-CI for lower LoA

• ci_u_loa_l_mover upper limit of 95%-CI for lower LoA

• ci_l_loa_u_mover lower limit of 95%-CI for upper LoA

• ci_u_loa_u_mover upper limit of 95%-CI for upper LoA
