I have the annual hospital costs for 5 million patients. Each patient can
be allocated to one of 36 age/gender groups. All patients are attached to a
general practice (n=8,000), and all practices are located within an
administrative area, a primary care trust (n=152). In other words, patients
are nested within practices which are nested within trusts.
How can I decompose the total variation in costs between those attributable
to the individual's age/gender, those attributable to the practice, and
those attributable to the trust?
Thanks.
Steve
