![]() You must have one column (or stored constant) for the number of trials (n) and one for the number of events (x). You can use Calc > Calculator to transform binomial data (proportions) or Poisson data (counts). For more information, see Knowledgebase ID 1959. Note: After applying a Box-Cox power transformation and analyzing the data in transformed units, you can create a contour plot to visualize the fitted regression or DOE model in the original units. IMPORTANT: Do not use Stat > Control Charts > Box-Cox Transformation to transform the response variable in a regression or DOE setting because this procedure does not take into account the relationship between the response and the predictors. Note: To display the command prompt, activate the Session window and choose Editor > Enable Commands. At the subcommand prompt (SUBC>), type influence. At the command prompt (MTB >) type %Bctrans C1 C2 C3 For instructions, see "How to save this page as a macro" at the top of the Code page.įor example, suppose the response variable is in C1, the predictors are in C2 and C3, and you want to display an index plot in addition to the default output. Save the page as a macro, called Bctrans.MAC, in your Minitab macros directory (in Minitab 16, the default location is C:\Program Files\Minitab\Minitab 16\English\Macros). (You can also click Documentation for more information about this test.)ģ. To the right of the Box-Cox Transformation for Regression and Response Surface Models description, click Code. Click the link, Box-Cox Transformation for Regression and Response Surface Models, below.Ģ. ![]() The influence of individual cases on the selection of lambdaġ. The values of the PRESS statistic transformed back to the original units over the 95% confidence interval The log-likelihood function with an estimate and 95% confidence interval for lambda To apply a Box-Cox transformation in DOE or to create charts of the optimization process for the Box-Cox lambda, use the Box-Cox Transformation macro available from our Macros Library. In Minitab 16, you can apply a Box-Cox transformation to response values in a regression analysis using Stat > Regression > General Regression. For example, if you have movable licenses of both Minitab 16 and Quality Companion installed on the same computer, using the Move License feature in either product will deactivate both products, and produce a single new product key that will activate both products on a new computer. The new Product Key will activate both products on the new computer. If multiple Minitab products are installed that are equipped with the Move License feature both products will be deactivated as part of one Move process. Therefore, you must install and activate a previous version of Minitab on the new computer prior to using the new key. Note: If you purchased an upgrade version, the new key produced by Move License will also be an upgrade key. Activate your software on a new computer using the Product Key created during the Move process. Click Save to text file to save the new Product Key to a location on your computer. Click Yes to confirm you want to deactivate the product on the current computer. Choose Help > Licensing to launch the Single-User License Utility. Also, in Quality Companion the Move License feature is only available in versions 3.2.1 and later. You activated the software using the Web Activation method You purchased a Timed or Fixed Duration License If you meet one of the following criteria, you cannot use the Move License feature: It deactivates the license on the current computer and generates a new Product Key to use on a new computer. The Move License feature allows a single-user license to be moved to a new computer without having to contact Tech Support.
