Splunk Core Certified Advanced Power User Practice Test

The function that provides the theoretical error of the estimated count of distinct values is specifically designed to accompany the estimation of distinct counts, which is crucial for understanding the accuracy of the results you're working with.

When using the `estdc` function to estimate the count of distinct values in your dataset, it often generates an estimated value. However, to assess the reliability and the potential variance of this estimation, the `estdc_error` function is utilized. This function calculates the theoretical error associated with the estimated count, helping users understand the range within which the true count of distinct values could realistically fall.

This error metric is particularly important in data analysis, where estimates can be subject to various levels of uncertainty. By using `estdc_error`, analysts can present more nuanced insights and make more informed decisions based on the distinct count of values. This reinforces the value of using estimating functions in Splunk effectively, as it allows users to not only get a count but also to gauge the credibility of that count.

In contrast, functions like `distinct_count` and `count` provide the actual counts but do not give information regarding the estimation errors, limiting the ability to evaluate the reliability of those counts.
