Why? Unlike descriptive statistics where we only describe the data at hand, hypothesis tests use a subset of observations, referred as a sample, to draw conclusions about a population..

The COMPUTE STATS statement performs the analysis, so a subsequent EXPLAIN statement has additional information to use in deciding how to optimize the distributed query. For more information and examples to help you interpret EXPLAIN output, see Using the EXPLAIN Plan for Performance Tuning. Extended EXPLAIN output:COMPUTE STATS Statement. Gathers information about volume and distribution of data in a table and all associated columns and partitions. The information is stored in the metastore database, and used by Impala to help optimize queries. For example, if Impala can determine that a table is large or small, or has many or few distinct values it can ...This program will compute statistics on segmented volumes. In its simplest invocation, it will report on the number of voxels and volume in each segmentation. However, it can also compute statistics on the segmentation based on the values from another volume. This includes computing waveforms averaged inside each segmentation. Synopsis"Compute" statistics is another option opposite to "Estimate". Can be run as on table as on index. If you create index with compute statistics it gathers stats on the index not on the table.

Often, one wants to compile statistics on what is going on in the optimization. The Statistics are able to compile such data on arbitrary attributes of any designated object. To do that, one needs to register the desired statistic functions inside the stats object using the exact same syntax as in the toolbox.Also if hive.compute.query.using.stats=true and statistics exists, then optimizer is using statistics for simple query (for example select count(col1) ...) calculation instead of querying table data (this may lead to wrong query results if …
