Modelling market risk: The AR1 model

YouTube • January 19, 2021 • 23:26

In this video we go through how to estimate AR(1)-models of market risk in the context of building a decision-support tool for risk management. The AR(1) model scores well on forecasting ability yet is simple and intuitive to use.

The AR(1) Model - Stationarity Condition and Properties Given Stationarity

YouTube • October 21, 2015 • 09:35

We present the stationarity condition for the AR(1) model and derive the properties of the model given stationarity.

OLS Estimation of the AR(1) Model

YouTube • February 20, 2017 • 07:44

We consider OLS estimation of the autoregressive parameter in the AR(1) model. Whenever the autoregressive paramter has true value between minus one and plus one, the OLS estimator is consistent.

Forecasting With a Stationary AR(1) Model

YouTube • October 27, 2015 • 09:18

We consider forecasting with a stationary AR(1) model. We derive the point forecasts and the variance of the forecasts one, two, and k periods ahead, and we show that these converge to the unconditional mean and variance, respectively, as the forecasting horizon goes to infinity.

Maximum Likelihood Estimation of the AR(1) Model

YouTube • February 20, 2017 • 10:10

We derive the likelihood function for the AR(1) model.

AR(1) Process: Mean, Variance, Autocovariance and Autocorrelation function.

YouTube • October 12, 2016 • 09:48

Full derivation of Mean, Variance, Autocovariance and Autocorrelation function of an Autoregressive Process of order 1 (AR(1)). We firstly derive the MA infinity respresentation of a stationary AR(1). Usng this we can then derive the relevant properties.
