Kunwar Nakul Rajput. Categorical overlays are shown by different colors or symbols. Prepare Your Data. Choose Main Matrix or Second Matrix, depending on whether you are importing dependent variables response variables or predictors or correlates of the response variables. We emphasize nonparametric tools, graphical representation, and randomization tests for analysis of community data.

For Summary Write Distance Matrix , fixed failure to write xls and xlsx formats when header lines are not included. Choose Main Matrix or Second Matrix, depending on whether you are importing dependent variables response variables or predictors or correlates of the response variables. The graph below used the same ordination scores as in the previous example, though not rotated. For ordination with 3 axes, rotation in one plane corrected in other views.

Multivariate Analysis of Ecological Data. Version 6. Cover: The essence of multivariate analysis is the extraction of a small number of important relationships from a very large number of possible relationships. By using this software you agree to this. Printed in the United States of America. Prepare Your Data. Open Your Data Files. Run an Analysis. Explore Your Results Graphically.

The terminology in the software is tailored for ecologists. We emphasize nonparametric tools, graphical representation, and randomization tests for analysis of community data. Very large data sets can be analyzed. Most operations accept a matrix up to 32, rows or 32, columns and up to ,, matrix elements, provided that your computer has adequate memory. Virtually any multivariate data set consisting of a set of entities, each with a number of measured attributes, is adaptable to PC-ORD. The possible formats for entering these data can be found in Data Preparation in the software help system.

Where is the Manual? Our context-sensitive Help system can be accessed at any time by pressing F1 or clicking a Help button.

How Do I Get Started? After you install the software, click on Help Contents in the main menu. Then navigate to Getting Started in the help system.

Right click, Rename Now set the working folder for that project. Generic instructions for a typical network setup are given below. Method 1 1. Right click on some free space on the desktop. Select: New Shortcut 3.

Enter the path for pcord6. Your network administrator can provide this path. Select: Properties Shortcut 7. Method 2 1. Double click on CreateDesktopShortcut. Important points 1. Each user needs a unique working folder directory. We recommend using a local drive rather than a network drive. This will speed the rate of screen refreshing when manipulating windows containing your data.

Recommended network setup 1. This allows users to preserve their own settings from one session to the next, regardless of which machine they are using. Limitations Most of the programs in PC-ORD for Windows can accept a matrix up to 32, rows or 32, columns, provided that you have adequate memory installed in your machine.

You can evaluate your memory needs with the Memory Requirements utility provided under the File menu. In this case, close out all programs, go through your normal shut-down procedure, restart, then try to rerun your analysis in PC-ORD. Our software support pertains only to programs obtained directly from MjM Software Design.

Updates and Fixes Fixes will be posted on the MjM website as needed. Click on Help Internet Support for the current web addresses for this and other aspects of internet support. Prepare your data. Run an analysis. Explore your results graphically.

Prepare Your Data For an easy start, follow the instructions in the help system exactly. Put your data in a spreadsheet e. Excel with the sample units as rows and variables as columns. Assign a short name to each row and column. PC-ORD will split the data set for you. File Import Matrix E.

Choose Main Matrix or Second Matrix, depending on whether you are importing dependent variables response variables or predictors or correlates of the response variables. You can do each set of variables, in sequence. You will be asked to select one worksheet to open. The Data Format dialog is displayed, allowing you to specify the content of the matrix: what the rows and columns are and where they are named. You must have column variable names. If you have no row names, you can generate them automatically with a check box.

Then use the following dialog to indicate which variables to extract and the variable type for each. In this case we selected all species for the main matrix.

Click OK and the matrix will be imported. Set up the second matrix in the same way example below. Open Your Data Files If you imported data in step 1, then proceed to step 3.

Open your second matrix in the same way: File Open Second Matrix. For the oak woods example, we might save the project as OakWoods.

Run an Analysis Select an analytical method. For this example, we will use nonmetric multidimensional scaling NMS or NMDS , one of the most powerful ordination methods, especially adept at extracting nonlinear gradients in species composition. This example uses the Oak Woods data set available for download at www. Select File Save as Result. Use a similar procedure to save the row and column coordinates, for example as NMSThil.

The minimum stress for the best 3D solution was Selected examples of these are shown below. These show relationships between variables in the second matrix and the ordination scores. Group 4 is relatively rich in species. The ordination has been rotated to align the strongest correlations with the horizontal axis. The graph below used the same ordination scores as in the previous example, though not rotated.

Much more informative than this static view is the capability to rotate this 3D picture continuously, allowing you to see the three dimensional structure more clearly. Categorical overlays are shown by different colors or symbols. Does not not affect graphing. In this case, a 2D solution is accepted only if further reduces stress by over 5 units. Fixed Modify Data Transpose Matrix with matrices with only one row or one column. Operation was blocked.

Fix for importing Excel. Changed measure of kurtosis to a more standard form, for example, that used in Excel The results differ appreciably only at small sample sizes. Improved method for scaling distance-based biplot.

For ordination with 3 axes, rotation in one plane corrected in other views. Changed action of Joint Plot so that it can be superimposed on any of the different kinds of ordination diagrams including vectors and grids. Added Plexus Overlay as option for ordination diagrams. This superimposes lines showing associations between species, based on standardized chi-square distances. Added Group Hide Categories menu option to ordination and scatterplot graphs to hide a selected set of points based on categorical variables in the second matrix.

Fixed enabling 3D graph animation menu item. Added 3D graph rotation dragging. Fixed Ordered Main Matrix spacing between elements.
