Permute! version 3.4 alpha 9
User's manualMultiple regression over distance, ultrametric and additive matrices with permutation testLast revision: Saturday, March 30, 2013Version HistoryDownload it hereImportantPermute! 3.4 is a major update to the Permute! 3.2 program, despite the small change in version number. It has been made easier to use, faster and more error-tolerant. Hopefully you will find this program to be highly usable, much more than the previous version. This is alpha software, which means it is usable and the feature list is almost complete but not totally implemented. What does Permute! do?This program computes a multiple regression of one or more independent variables over one dependent variable, and assesses the probability (p-value) of the regression coefficients and the associated R2 (R-squared) using a permutational method described in Legendre, Lapointe and Casgrain (1994). It also allows the user to select the variables that contribute most to the variation through several procedures: backward elimination, forward selection and stepwise regression.The program is remarkable in its use of appropriate permutation methods. If the variables represent distance matrices, ultrametric or additive trees, the permutation method accounts for it by generating a permuted distance matrix or tree. How to use the programKeeping with the philosophy of Macintosh programs, the author assumed that users do not like to read manuals. Hence the program's interface is as self-explanatory as possible, and has balloon help throughout. However, it assumes that the user is familiar with the contents of the Legendre, Lapointe and Casgrain (1994) paper, or at least with the concepts of multiple regression. To start the program, double-click on the icon. From the 'File' menu, choose 'Open...' and select your input file (see below for the file's format). You can also drag your input file and drop it on the program's icon. After a short delay, your file should appear in its own scrollable and resizable window, to show you what the program has read. You can then be sure that the program read your data file correctly. NoteThe program has no way of knowing if your data file is corrupt. You should at least make a visual check on your data to ensure it has been read correctly.About threads... Starting with version alpha 2, the program is multi-threaded, allowing the user to run multiple, concurrent analyses and background tasks. This requires the Thread Manager, part of System 7.5 and later. You can also get an extension for earlier systems. The 68k and PPC versions will be multi-threaded if the Thread Manager is present.When at least one data file has been read, the File menu's 'New analysis' item is enabled. Choosing it will cause the 'Multiple regression' window to come to the front of the screen. If you have opened more than one data window, the multiple regression will be carried out for the topmost data file. The multiple regression window looks like this: The names of the variables will be different for your own data file. The features of this window are as follows:
