Given a variable y indexed by a time vector x, calculates the compound annual growth rate. Note that CAGR assumes
that the x refer to years. Also it is only calculated using the first and latest observed values.
Usage
CAGR(y, x)
Value
A scalar value (CAGR)
Arguments
y
A numeric vector
x
A numeric vector of the same length as y, indexing y in time. No NA values are allowed
in x. This vector is assumed to be years, otherwise the result must be interpreted differently.
