What exactly is recorded in Master Macros?
Datafile selections.
The recording of the Master Macro begins when you select Start
Recording Log of Analyses (Master Macro) from the Tools
- Macro menu. If you select an input datafile after you start the
recording, then the selection of that file will become part of the Master
Macro. For example, suppose you opened a file and then started a Multiple Regression analysis; the recorded
macro would include the following lines:
...
Dim
S1 As Spreadsheet
Set
S1 = Spreadsheets.Open
("c:\datasets\OilAnalysis.sta")
S1.Visible
= True
Dim
newanalysis2 As Analysis
Set
newanalysis2 = Analysis (scMultipleRegression,S1)
...
The input datafiles selection was explicitly recorded, and the Multiple Regression was initialized
using the datafile that was explicitly opened for this analysis. Hence,
if you run this Master Macro, the analysis will be performed on the same
datafile, i.e., it will be loaded from the disk prior to the Multiple
Regression analysis.
Now suppose you started the recording of the Master Macro after you
had already selected and opened an input datafile. The same analysis might
be recorded like this.
...
Dim
S1 As Spreadsheet
Set
S1 = ActiveSpreadsheet
Dim
newanalysis2 As Analysis
Set
newanalysis2 = Analysis (scMultipleRegression,S1)
...
Now the recording started by defining as the input datafile the currently
active input spreadsheet. If you run this Master Macro, the Multiple
Regression analysis would be performed on the currently active
input datafile, i.e., possibly a different datafile than that used while
recording the Master Macro.
Data editing operations.
Certain data editing operations on an input spreadsheet (datafile) are
recorded as part of Master Macros. As a general rule, most editing operations
that are accomplished via selections on respective dialogs (e.g., the
Sort Options dialog) are recorded;
operations that are performed via simple keyboard actions (e.g., deleting
a data value by pressing the Delete
key on your keyboard) are usually not recorded. Also keep in mind that
the Master Macro recording only starts when the recording is explicitly
requested; so any editing operations that are performed prior to the start
of the recording of course will not be reflected in the Master Macro.
Here is a list of data editing operations that are recorded into Master
Macros:
Most operations available on the Data
menu are recorded.
Sorting
Creating subsets of cases or variables
Changes in the variable specifications
Data transformations via formulas entered into
the specifications dialogs of the respective variables
Adding, moving, copying, and deleting variables
Adding, moving, copying, and deleting cases
Ranking of data
Recoding operations
Automatic replacement of missing data operations
Shifting of data
Standardizing data
Date operations
Recordable operations performed outside the Data
menu, include:
Creation of new datafiles (spreadsheets)
Opening datafiles
All Output Manager
options
Filling data ranges with random values (note that
this operation is recorded even though it is accomplished without going
through dialogs, but by selecting it from the Edit
menu)
Entering case selection conditions on a global
and local (one analysis) level
Entering case weight variables on a global and
local (one analysis) level
Note that recording of certain operations as part of the Master Macro
logs might lead to creating ambiguous and context-dependent solutions,
so they are excluded from the list of recordable tasks. This includes
such operations as:
Editing values in the spreadsheets
Selections of cells
Clipboard based copy, paste, and delete operations
(note that this does not include the copy, move, and delete cases and
variables operations listed above)
Generally, anything not on the list of recordable
data management operations (see above).
Keep these issues in mind when recording a Master Macro with data editing
operations that are necessary before subsequent analyses are performed.
Recording consecutive
and simultaneous analyses. To reiterate, Master Macro recordings
will reproduce the exact sequence of analyses and output choices (of results
spreadsheets or graphs) made during the analysis. This facility provides
great flexibility and even allows you to "string together" analyses
so that the first one computes certain results, while the second one analyzes
those results further. For example, you could first perform a Multiple
Regression analysis on a particular datafile, then use the option
Save on the results dialog of
the Multiple Regression analysis
to create a stand-alone input spreadsheet of predicted and residual values
from the analysis, and then compute Basic
Statistics on the numbers in that spreadsheet. The Master Macro
recording of that sequence of analyses would look something like this:
...
Dim
S1 As Spreadsheet
Set
S1 = Spreadsheets.Open
("c:\STATISTICA\OilAnalysis.sta")
S1.Visible
= True
Dim
newanalysis1 As Analysis
Set
newanalysis1 = Analysis (scMultipleRegression,S1)
...
Dim
newanalysis2 As Analysis
Set
newanalysis2 = Analysis (scBasicStatistics,ActiveDataSet)
With
newanalysis2.Dialog
.Statistics = scBasDescriptives
End With
...
Note how consecutive analyses (objects) are enumerated as newanalysis1
and newanalysis2. The first one
(Multiple Regression) is initialized
with an explicit input datafile; the second one is initialized with the
currently active dataset. When recording complex sequences of analyses
like these where results of one analysis serve as the input for subsequent
analyses, extra care must be taken to review and, if necessary, edit the
final macro before running it to ensure that the intended sequence of
ActiveDataSets are chosen by
the respective analyses.
Case selection conditions,
case weights. Like Analysis Macros, when case selection conditions
or case weights are specified during an analysis, those actions are properly
recorded in the Master Macro. However, in addition, when you specify case
selection conditions and case weights globally for the datafile (i.e.,
outside any specific analysis), those actions are recorded as well.
Handling output: Sending
results to workbooks, reports, etc. Like Analysis Macros, when
case output options are changed during an analysis, those selections are
recorded in the macro. In addition, if global output defaults are changed
via the Tools - Options menu
(on the Output Manager tab of
the Options dialog), then those
choices are recorded into the Master Macro as well. Therefore, if you
started a Master Macro, then set the global Output
Manager option to direct all results spreadsheets and graphs to
separate workbooks (for each analysis) as well as to reports, then those
selections will be recorded in the Master Macro and reproduced when you
execute that macro.
Master Macro recording
and Analysis Macro recording. The two major modes of macro recording
- Master Macros and Analysis Macros, which are always being recorded in
the "background" - can be used simultaneously. In other words,
you can make Analysis Macros while recording a Master Macro. However,
note that the action of creating the Analysis Macro is not itself recorded
in the Master Macro.
