In unvs.med: A Universal Approach for Causal Mediation Analysis

Bootstrapping Estimation for Causal Mediation Effects via Multi-threading Process

Description

This function obtains the estimates of mediation effects via non-parametric bootstrapping. Through bootstrap sampling and repeating the algorithm of function SingleEstimation, This function obtains a number of estimates for each type of effect.

This is an internal function, automatically called by the function Statistics.

Usage

BootEstimation_MT (m_model, y_model, data, X, M, Y,
m_type, y_type, boot_num = 100)

Arguments

m_model	a fitted model object for the mediator.
y_model	a fitted model object for the outcome.
data	a dataframe used in the analysis.
X	a character variable of the exposure's name.
M	a character variable of the mediator's name.
Y	a character variable of the outcome's name.
m_type	a character variable of the mediator's type.
y_type	a character variable of the outcome's type.
boot_num	the times of bootstrapping in the analysis. The default is 100.

Details

This function activates the multi-threading process through package 'snowfall' in R with max-1 cores (CPU) of the PC.

Value

This function returns a list of three dataframes, i.e., the bootstrapping results of the mediation effects. This list is also saved in the return of the main function FormalEstmed.
