# Title: Conditioning on a Collider

# Description: Directed acyclic graphs (DAGs) are a great tool that can be 
# used to guide variable selection. Colliders, a variable where two arrowheads meet, 
# should not be adjusted for since they can induce bias. This code aims to prove
# and quantify the bias using a simple example.

# Title: Demonstration of the Central Limit Theorem

# Description: The purpose of this script is to simulate data for three different 
# distributions (normal, logistic and poisson) for four different sample sizes. 
# Each of these is then plotted to demonstrate how the sampling distribution 
# changes with increasing sizes of the sample.

# Title: Calculating Probability of Censoring

# Description: Inverse probability of censoring weighting (IPCW) can be used to remove the potential selection bias 
# caused by censoring. There are different ways to calculate the probability of censoring. The goal of this code was 
# to examine whether the two methods produced the same result.
