8                Statistical stability, reported in the data table, is based on a statistic
9                called the "Relative Standard Error," or RSE, which is the standard error
10                expressed as a proportion of the point estimate (e.g., 30% of the point
11                estimate).
12        </TEXT>
13        <TEXT>
14                A dash (-) means that the relative standard error (RSE) is below 0.30
15                and the count or rate may be considered stable.
16        </TEXT>
17        <TEXT>
18                "Unstable" is displayed when the RSE is 0.30-0.50. An unstable count or rate
19                may fluctuate widely across time periods due to random variation (chance).
20        </TEXT>
21        <TEXT>
22                "Very Unstable" is displayed when the RSE is  greater than 0.50. A very
23                unstable count or rate should not be used to inform decisions. You may
24                combine years or otherwise increase the population size used in the query
25                to achieve a more stable count or rate.
26        </TEXT>

28                Problems with statistical instability typically occur when there is a small
29                number of health events in a small population. For more information on
30                statistical stability, visit the NM-IBIS Reliability &amp; Validity page
