<code>cfi</code> returns a summary dataset containing the multimorbidity weighted index
for each patient.

Identifying comorbidities, frailty, and multimorbidity in claims
and administrative data is often a duplicative process.
The functions contained in this package are meant to first prepare the data to a format
acceptable by all other packages, then provide a uniform and simple approach to
generate comorbidity and multimorbidity metrics based on these claims data. The package
is ever evolving to include new metrics, and is always looking for new measures to include.
