Returns suitably lagged and iterated quotients

Quot(x, lag = 1, quotients = 1, ...)

If x is a vector of length n and quotients = 1, then the computed result is equal to the successive quotients

x

n

quotients = 1

x[(1+lag):n] - x[1:(n-lag)].

x[(1+lag):n] - x[1:(n-lag)]

If quotients is larger than one this algorithm is applied recursively to x. Note that the returned value is a vector which is shorter than

quotients

x.

If x is a matrix then the division operations are carried out on each column separately.

a numeric vector or matrix containing the values to be used for calculating the quotients.

an integer indicating which lag to use.

an integer indicating the order of the quotient.
