steiger_sensitivity: Evaluate the Steiger test's sensitivity to measurement error

In MRCIEU/TwoSampleMR: Two Sample MR Functions and Interface to MR Base Database

Evaluate the Steiger test's sensitivity to measurement error

Description

Evaluate the Steiger test's sensitivity to measurement error

Usage

steiger_sensitivity(rgx_o, rgy_o, ...)

Arguments

rgx_o	Observed variance of exposure explained by SNPs
rgy_o	Observed variance of outcome explained by SNPs
...	Further arguments to be passed to lattice::wireframe()

Value

List with the following elements:

vz

Total volume of the error parameter space

vz0

Volume of the parameter space that gives the incorrect answer

vz1

Volume of the paramtere space that gives the correct answer

sensitivity_ratio

Ratio of vz1/vz0. Higher means inferred direction is less susceptible to measurement error

pl

plot of parameter space
