It is also possible to lag terms by using the suffix (-i) for the ith lag, i.e. Likewise, the ar(1)Īnd the ma(2) term refer to a first autoregressive term For example, the c in the formula refers to the constant term in the regression. these cannot be used as independent variable The wizard also recognizes some words as reserved, i.e. The specification for the standard OLS-regression may be given by the formula:ĭependent_variable c independent_variable1 independent_variable2 … This provides a wizard for estimating equations: The easiest way to run regressions in EViews is done using Quick -> Estimate Equation: The menu in View-> Descriptive Statistics & Tests also provides useful graphs – notably Histogram and Stats This can be used to draw the traditional graphs as well as the Q-Q plot for checking/testing distributions.

The easiest way to draw graphs is to open the series spread sheet and use View -> Graph which generates a The residual seriesĬan be generated from the equation box by using Proc -> Make Residual Series… : This may be used to gauge the goodness of the model.
Thus, it is possible to generate the returns series by theĮViews also provides the possibility of generating residual series for regression models (running the actual Observation is natural logarithm of the old series series, i.e.Ī new series diffseries where each observation is the difference of two concurrent observations in series, The first generates a new series lnseries where each Some of the more useful transformations are the logarithmic transformation: lnseries = log(series) and theĭifference transformation: diffseries = d(series).
This can be done in EViews by using Quick -> Generate Series… : For example, one may have to transform a price series Usually it is necessary to edit the imported raw data. Transformations and generating new series If the copied data is larger than the workfile-specific sample size,ĮViews automatically drops the ”excess” data. To copy paste the data it is necessary to enable editingīy right clicking the series spread sheet:Īfter this the data may be copy pasted. This generates a new series in the workfile window. In order to copy paste it is first necessary to generate a new blank series. it is tedious to import new data with sample size 1000 to a workfile that has existing The drawback to this method is the fixed sample sizeįor the work file, i.e. xls-files.ĭata may also be copy pasted to an existing workfile.
This starts a ready-made and easy-to-use wizard for importing data from. The easiest way to import data to Eviews is perhaps to use File -> Open -> Foreign data as Workfile Transformations and generating new series.
