ICCbin

An R package facilitating clustered binary data generation, and estimation of Intracluster Correlation Coefficient for binary data

Functions

Data generation

• rcbin() — Generates correlated binary clustered data given an ICC, event proportion, number of clusters, cluster size, and percent variation in proportion and cluster size.
• rcbin_flex() — An enhanced alternative to rcbin() that uses a Beta distribution for cluster-specific event proportions and supports overdispersed cluster sizes via the Negative Binomial distribution. Unlike rcbin(), the prvar and csvar parameters represent actual variances rather than percentages.

ICC estimation

• iccbin() — Estimates ICC for binary clustered data using 16 methods and 5 types of confidence intervals.
