Anota:
Analysis of Tables
Version 7

Overview of the menu system of the program

File menu

The File menu contains the following options: Create a new Anota file by entering variables names, category labels, and all bivariate tables. Read an existing Anota file. Anota files always have the extension tbl. Stop program execution. Changes in a data file will be saved.

Edit menu

Use the Edit menu to make changes in an existing data file. The only changes your are allowed to make, are modifying the names of the variables and the labels of the categories of the variables, and modifying the values in the cells of the tables. It is not possible to change the number of categories of a variable, or the number of variables.

You will only succeed in activating the Edit menu after you have specified a data set to work with. So before you can do something with Edit, the program first has to read the data with one of the options of the File menu.

The Edit menu contains the following options:

Select the variable to be modified. You can change its name, and the names of its categories. If you activite this option, the first table will appear on the screen. You can make changes in the values in its cells.

By clicking on the appropriate button, you can go to the next or previous table. The tables are processed in the following order: V2 x V1, V3 x V1, V3 x V2, V4 x V1, V4 x V2, V4 x V3 ...

It should be noted that tables must be consistent, i.e. the marginal totals of a variable must be the same in each table in which this variable appears. If the tables are not consistent, it is not possible to carry out an analysis.

Model menu

Use the Model menu to specify the model to be analysed and to look at the results of the analysis. The Model menu has the following options: All available variables are listed in a column in the middle of the window. You select a dependent variable by moving one of these variables to the left, to the field with the name Dependent. You move a variable by selecting it in the middle column and clicking on the blue arrow-left button. You can move a variable back by selecting it in the field on the left, and then clicking the red arrow-right button.

You select a predictor variable by moving a variable in the middle column to the right, to the column with the name Predictors. You move a variable by selecting it in the middle column and clicking on the blue arrow-right button. You can move a variable back by selecting it in the column on the right and then clicking the red arrow-left button.

After you have specified your model, click on the Compute button to start computation. Note that computation can only be carried out if you specified a dependent variable and at least one predictor variable.

After computations have been completed, you first get an overview of the range of the estimates for the categories of the dependent variable. These estimates should lie within the range from 0 to 100. Negative values or values above 100 usually indicate an ill-fitting model.

After clicking on the OK button, the estimates are displayed on the screen. For each predictor variable there is a table with estimates. The values in the cells are the contributions of the categories of the predictor variables to the estimates of the percentages in the categories of the dependent variable. You can see these values as deviations from the precentages in the Average column. A contribution is only significant if its values is displayed in bold-face.

Note that values in the column Averages sum to 100%, and that the weighted values in a row of a table sum to 0%.

By pressing on the "Next" button you go to the next table of estimates. By pressing on the "Previous" button you go to the previous table of estimates.

Use this option to have another look at the estimates after the computations have been completed. For each predictor variable there is a table with estimates. The values in the cells are the contributions of the categories of the predictor variables to the estimates of the percentages in the categories of the dependent variable. You can see these values as deviations from the precentages in the Average column. A contribution is only significant if its values is displayed in bold-face.

Note that values in the column Averages sum to 100%, and that the weighted values in a row of a table sum to 0%.

By pressing on the "Next" button you go to the next table of estimates. By pressing on the "Previous" button you go to the previous table of estimates.

Output menu

Use the Output menu to produce a report. You can either make a simple text file or an HTML file. You also have some choices of what to include in the report.

The Output menu only has one option:

There is a set of radio buttons that controls the type of output file. You can choose for either a file in HTML format or a simple text file.

There is an input field in which can enter the name of the output file.

There is also a set of check buttons that controls the components that are included in the output file. The following options are available:

Help menu

The Help menu provides information about the program. There are two options:

This option gives access to the help system. This option gives information about the current version of the program.
