Normalize Year-Period Array

This function normalizes a numerical array c(YEAR,PERIOD), given a frequency f and PERIOD>=f.

e.g. normalizeYP(c(2000,15),12) = c(2001,3)

normalizeYP(x = NULL, f = NULL)

Arguments

• x: Input numerical array c(YEAR,PERIOD)
• f: Frequency of normalization. Must be a positive integer.

Returns
