REGRESSION WITH TIME SERIES VARIABLES

•Regression modelling goal is complicated when the researcher uses time series data since an explanatory variable may influence a dependent variable with a time lag. This often necessitates the inclusion of lags of the explanatory variable in the regression. •If “time” is the unit of analysis we can still regress some dependent

Unit Root & Augmented Dickey-Fuller (ADF) Test

Dickey-Fuller Tests • If a constant or trend belong in the equation we must also use D-F test stats that adjust for the impact on the distribution of the test statistic (* see problem set 3 where we included the drift/linear trend in the Augmented D-F test). • The D-F is generalized into the Augmented D-F test to accommodate the general

Solutions Manual for Statistical Inference, Second Edition

second edition, problems were shuffled with no attention paid to numbering (hence no attention paid to minimize the new effort), but rather we tried to put the problems in logical order. A major change from the first edition is the use of the computer, both symbolically through Mathematicatm and numerically using R. Some solutions are given ...

APPLIED ECONOMETRIC TIME SERIES (4th edition)

1. Looking at the time path of a series is the single most important step in forecasting the series. Examining the series allows you to see if it has a clear trend and to get a reasonable idea if the trend is linear or nonlinear. Similarly, a series may or …

Lecture 13 Time Series: Stationarity, AR(p) & MA(q)

RS –EC2 -Lecture 13 3 • We want to select an appropriate time series model to forecast yt. In this class, the choices are AR(p), MA(q) or ARMA(p, q). • Steps for forecasting: (1) Identify the appropriate model. That is, determine p, q. (2) Estimate the model. (3) Test the model.

3 Construction of an ARIMA model 1. Stationarize the series, if necessary, by differencing (& perhaps also logging, deflating, etc.) 2. Study the pattern of autocorrelations and partial autocorrelations to determine if lags of the stationarized series and/or lags of the forecast errors should be included in the forecasting equation 3.
