Which command is used for advanced statistical calculations in Splunk?

The command used for advanced statistical calculations in Splunk is "stats." This command is specifically designed to perform statistical operations on sets of data in your events. It enables a wide range of calculations such as sum, average, count, min, max, and standard deviation, which can be aggregated across various fields. The stats command can also create results in a tabular format, making it easier to analyze complex data sets and extract meaningful insights.

Other commands serve different purposes. For example, "eval" is used to create new fields or transform existing ones by evaluating expressions, while "chart" generates statistical visualizations based on the data but has a more limited scope compared to stats. The "collect" command is utilized to collect results from a search and store them in a summary index, which is useful for archiving but not for performing statistical calculations directly. Therefore, the stats command is the most appropriate choice for performing advanced statistical tasks within Splunk.
