Sometimes it can be convenient to see the concrete value of control variables in a line, but this does not make it easier to locate the line in a command file… But EViews inserts concrete values from control variables, so the user may receive an error like “!m is not defined or is an illegal command in ‘!m = 0 + 0′”, in stead of a raw depiction of the line (“!m = !m + !k”). The user can see the file involved, and how the offending line looks. This is not very user-friendly when running larger files/systems. Apparently, EViews does not provide the line number, when errors occur, neither for marked blocks of commands (run from the command window), or from batch/command files run with EXEC.So these two lines must be executed as one block, and cannot be tried out separately. After the first line is executed, %s no longer exists in memory when it is to be shown in the second line (this variable only seems to live while the first line is executing). But even if the user does this, there is for instance a problem with executing the lines “%s = “hello”” and “show %s” one by one. The only way to run a single command line seems to be to mark it, right-click it, and choose ‘Run selected’ (for which there is no short-cut). The EViews user can run a whole file ‘batch’, or a block of commands can be marked and executed by right-clicking and choosing in the menu.

It does not seem possible to obtain a line-by-line execution of commands (like in Gekko or AREMOS or other packages).

This will result in quite a lot of copying, and then the user must remember to delete these objects afterwards. For instance “copy wf1::page1\ser1”, but it does not seem possible to use “wf1::page1\ser1” in expressions (in contrast to Gekko’s use of colon). These have to be copied/cloned first, before use.

It does not seem possible to refer directly to objects on other pages or workfiles.

The databank/workfile format seems proprietary and undocumented, in contrast to the open-format Gekko databanks (protobuffers). So if there are several frequencies, these seem to have to live on separate pages in the workfile. Workfiles can have ‘pages’ (a bit like tabs in Excel), and for each page there seems to be a global sample period (defined once and for all) and fixed frequency.

When you open up EViews with a new ‘workfile’, it seems a bit cumbersome that the user always as the first thing has to pick out a sample (period) for the work file.

The following points may be biased, or even wrong (comments are appreciated), but they reflect an honest attempt to perform some timeseries related tasks in EViews, as compared to running them in Gekko. It is not the intention here to judge the EViews capabilities regarding model solving or econometrics, but instead we will take a look at EViews for data management purposes (on timeseries data).

The comparison is limited to data management purposes, where the following questions can be raised. (This section is taken originally from the user manual) EViews for data management purposesĮViews is indeed a polished and professional software product.

Please note that since then, Gekko 3.0 has been released, containing many new features compared to 2.0. For Timberlake training courses in EViews 9 please visit this page.This section compares EViews (version 8) modules and functionality with Gekko 2.0 (as of December 2015). To see a video of the command capture window feature, and other new features of EViews 9 please visit this page. For convenience, the command capture can also be closed.įor those who prefer to maintain records of procedures done, the command capture feature is a fantastic new addition to EViews 9.

All the commands captured in the command capture window can be easily converted to a program for future use. The window can be docked or moved around to your preferred position, including outside the EViews 9 desktop.

The command capture window allows the user to save the code for most operations for further use. While the first method allows users to follow the menus and dialogs to guide them through defined procedures, the second method is command based allowing researchers to create a program with all of their procedures for future manipulation and editing.ĮViews 9 introduces a command capture window that displays the command for essentially every procedure done in EViews 9. Researchers interact with statistical software in two ways: the first is using the point and click interface and the second is through the command window.
