Standardized Innovations

Description

Standardizes Kalman filter innovations. This is a helper function called by MARSSinnovationsboot() in the MARSS-package. Not exported.

Usage

stdInnov(SIGMA, INNOV)

Arguments

SIGMA

n x n x T array of Kalman filter innovations variances. This is output from MARSSkf.

INNOV

n x T matrix of Kalman filter innovations. This is output from MARSSkf().

Details

n = number of observation (y) time series. T = number of time steps in the time series.

Value

n x T matrix of standardized innovations.
