Select or highlight the code for the macro, beginning with the word “macro”, and ending in
“endmacro”.
Choose Edit > Copy.
Open Notepad and choose Edit > Paste.
Choose File>Save As and type the file name in double-quotes including the .mac extension.
The name of the macro is typically listed below the “macro” line in the body of the macro.
For example, “BARTLETT.MAC”.
Save the file to the macros folder under the main Minitab directory.
In Minitab, invoke the macro in the Session window or Command Line Editor by typing %,
followed by the macro name. For example, %BARTLETT.
If you still have questions, you can e-mail us.
You may need to set up a folder for your Macros. You need to be sure that Minitab
can find this folder. I find it convenient to prepare and save a dummy worksheet
using Minitab and to store it in the same file in which the Macros are kept. Mine is
called ‘notmuch.mtw.’ This worksheet can have absolutely anything on it. Then,
when the macros are called, there is no problem finding them. You simply use the
‘editor’ pull-down menu to ‘enable commands.’ When you want to use the macro,
use the ‘file’ pulldown menu to load your worksheet. Minitab will assume that the
macro is in the same file. Use Notepad to open the macro to get instructions on how
to use it.
Macros below are classified as ‘General Statistics,’ ANOVA and Regression’ and
‘Nonparametrics.’ These and much more are available at
http://www.minitab.com/support/macros/

Median Smoother
This macro calculates a median smoother with a default span of 3. The 1st observation of
the smoothed data is the median of the 1st 3 data points (X1, X2, X3). The 2nd observation
of the smoothed data is the median of the (X2, X3, X4). The 3rd observation is the median
of (X3, X4, X5)… Thus, the smoothed data represents a moving median of the original data.

are replaced by "steps" between the known values.

Box-Cox Transformation for Regression and Response Surface Models
This macro determines the likelihood estimate of the Box-Cox power transformation
parameter in regression and response surface modeling applications. A plot of the loglikelihood function over a range of parameter values is displayed showing the likelihood
estimate and an approximate 95% confidence interval for the parameter. Also displayed is
a plot of the values of the PRESS statistic transformed back to the original response scale
over the 95% confidence interval. Optionally, the user may choose to specify the range of
parameter values in the plot of PRESS, display an index plot due to Cook and Wang (1983)
showing the influence of individual cases on the likelihood estimate, and store all computed
results.

Multiple Case Cook's Distance
This macro computes the multiple case extension of Cook's single case distance measure.
Depending on the data set size, the distance measure can be computed for all case pairs
and triplets. In addition, the distance measure can be computed for user selected subsets
of up to ten cases. Graphics produced include a plot of Cook's distance for single cases
against case number, an influential case pairs ID plot, and fixed-pair effect plots which
display the effect, or change in Cook's distance, due to adding a third case to a fixed pair of
cases. Like functionality is available for models with no constant term.

trend in the data.
