Provides the periodicity of an extracted data item. This is the number of submitted varified values per day. As such, the range, boundary and duplication varification methods must have been first run. Periodicity is only defined for 2d data.

verify_periodicity(x, los_table)

Arguments

x

an extracted events table

los_table

episode length table

Value

x with a periodicity value and validation columns

Details

As periodicity for dataitems is not yet specified, this highlights cases that are below the group 5th centile -1 and above the 95th centile +1

This is a similar concept to the coverage, although is concerned with the episode, rather than site, level.
