How do I calculate percentage change over period (Y/Y, Q/Q, P/P, M/M)?

There are two main possibilities to calculate percentage changes:

1. The Rate of Change analysis

Set the Method as “Change over period %”, and then choose the length.

2. Formula

You can also calculate percentage change over period with the formula:

cop(series, length)

Examples for Y/Y, M/M and Q/Q changes, respectively:

cop(segdp, YearsLength(1))

cop(segdp, MonthsLength(1))

cop(segdp, QuartersLength(1))
