yearOverYearIndexes {IndexNumR}

Estimate year-over-year indexes

Description

Year-over-year indexes are indexes where the months or quarters of the year are split in separate datasets and an index estimated on each. Therefore, year-over-year indexes estimated on a dataset with five full years of observations at a monthly frequency will have 12 separate indexes, each with 5 observations.
