What Is Too Much Variation? The Null Hypothesis In Small-Area Analysis, Paula Diehr
What Is Too Much Variation? The Null Hypothesis In Small-Area Analysis, Paula Diehr
Paula Diehr
A small-area analysis (SAA) in health services research often calculates surgery rates for several small areas, compares the largest rate to the smallest, notes that the difference is large, and attempts to explain this discrepancy as a function of service availability, physician practice styles, or other factors. SAAs are often difficult to interpret because there is little theoretical basis for determining how much variation would be expected under the null hypothesis that all of the small areas have similar underlying surgery rates and that the observed variation is due to chance. We developed a computer program to simulate the distribution …
