Convenience wrapper converting raw moments about origin a
to central moments (about the mean).
Usage
raw2central(raw_moments, origin = 0)
Arguments
- raw_moments
Numeric vector of raw moments about origin
(orders 1..K).
- origin
Initial origin (default 0).
Value
Numeric vector of central moments (orders 1..K).
Examples
x <- c(20, 25, 29, 32, 40)
raw_direct <- sapply(1:5, function(r) mean(x^r))
raw2central(raw_direct, origin = 0)
