Disaggregating a series
In this exercise, we’ll use a formula to disaggregate a series. Normally, you can do this with a simple rate of change, but sometimes you’ll want to use a formula to specify some additional conditions.
In this case, we want to disaggregate the series cntrad1290 (China Current Prices, Total, Aggregate, CNY). This is Chinese data that is aggregated on a yearly basis and does not have values for January. Therefore, we’ll need to disaggregate only the values from March to December and split the February value between January and February.
