Chapter 29: Time Series Analysis

Chapter Introduction
Module 29.1: nag_tsa_identify - Time Series Analysis - Identification
nag_tsa_acf Calculates the sample autocorrelation function of a univariate time series
nag_tsa_pacf Calculates the sample partial autocorrelation function of a univariate time series
Examples
Module 29.2: nag_tsa_kalman - Kalman Filtering
nag_kalman_init Provides an initial estimate of the Kalman filter state covariance matrix
nag_kalman_predict Calculates a one step prediction for the square root covariance Kalman filter
nag_kalman_sqrt_cov_var Calculates a time-varying square root covariance Kalman filter
nag_kalman_sqrt_cov_invar Calculates a time-invariant square root covariance Kalman filter
Examples
Module 29.3: nag_tsa_spectral - Time Series Spectral Analysis
nag_spectral_data Calculates the smoothed sample spectrum of a univariate time series
nag_spectral_cov Calculates the smoothed sample spectrum of a univariate time series using autocovariances data
nag_bivar_spectral_data Calculates the smoothed sample cross spectrum of a bivariate time series
nag_bivar_spectral_cov Calculates the smoothed sample cross spectrum of a bivariate time series using autocovariances data
nag_bivar_spectral_coh Calculates the squared coherency, the cross amplitude, the gain and the phase spectra
nag_bivar_spectral_lin_sys Calculates the noise spectrum and the impulse response function from a linear system
