Discrete Integration: Inverse of Differencing

Computes the inverse function of the lagged differences function diff.

Keywords
ts
Usage
diffinv(x, ...)

# S3 method for default diffinv(x, lag = 1, differences = 1, xi, …) # S3 method for ts diffinv(x, lag = 1, differences = 1, xi, …)

Arguments
x

a numeric vector, matrix, or time series.

lag

a scalar lag parameter.

differences

an integer representing the order of the difference.

xi

a numeric vector, matrix, or time series containing the initial values for the integrals. If missing, zeros are used.

arguments passed to or from other methods.

Details

diffinv is a generic function with methods for class "ts" and default for vectors and matrices.

Missing values are not handled.

Value

A numeric vector, matrix, or time series (the latter for the "ts" method) representing the discrete integral of x.
