aicbic()

aicbic function returns the top 5 aic and bic values for an ARMA time series

ase()

ASE calculator (specific to tswge) Takes the last length(xhat) entries in x and compares them to xhat

assess()

assessment function! assess a time series

calculate_ar1_varx()

Computes the Population Variance of an AR(1) Time Series

calculate_arp_varx()

Computes the Population Variance of an AR(p) Time Series Note that this can also be used for AR(1) models instead of using calculate_ar1_varx although, it will need an extra argument 'pt'

calculate_ts_gamma()

Computes Gamma (Auto Covariance of a time series realization)

calculate_ts_gamma0()

Computes Gamma0 (Variance of a time series realization)

calculate_ts_mean()

Computes the Mean of a Time Series realization

Computes the Variance of the Sampling distribution of the Mean of a Time Series

check_stationarity()

Wrapper to check the stationarity of a Time Series

compute_a()

Given an AR(p,q) realization, this function estimates the white noise estimates using equation 6.23 (from the text book)

compute_stda()

Given the white noise estimates, this function computes the standard deviation of the white noise. Note that non-zero terms are removed before calcualting the variance.

compute_vara()

Given the white noise estimates, this function computes the variance of the white noise. Note that non-zero terms are removed before calcualting the variance.

difference()
