Workspace Node: Breakdown Non-Factorial Tables - Specifications - Quick Tab

The Breakdown Non-Factorial Tables workspace node can be accessed from the Feature Finder, ribbon bar, or Node Browser. The Quick tab of the specifications dialog box is displayed by default when you double-click the node.

Element Name Description
Variables Click the Variables button to display the standard variable selection dialog box, in which you can select a set of grouping (categorization) variables and the dependent variables to be subcategorized. For each dependent variable, breakdown tables will be computed for all possible combinations of grouping variables. Note that Statistica automatically takes all valid integer codes in the respective grouping variables to construct the tables. A breakdown variable also can be continuous in nature. In this case, each distinct value of the breakdown variable will define a single group (category). To select a continuous variable as a breakdown variable, first clear the Show appropriate variables only check box, located in the lower-left corner of the variables selection dialog box to display all the variables in the data set in the variable lists.
Options This group box contains options concerning the output summary spreadsheet.
Sorted Output Select this check box to sort the output in this manner: 1) all values with text labels alphabetically, 2) then all non-text numerically, and 3) then the missing data code last.
Include "all missing" category When this check box is selected, missing data in all specified grouping variables will result in new categories being defined in the output spreadsheet.
Include total (All Groups) row This check box is selected by default. When the check box is cleared, all internal computations are unchanged, but the All Groups row (totals of all groups) is not created in the output spreadsheet.
Weighted moments Select the Weighted moments check box to specify that each observation contributes the weighting variable's value for that observation. The weight values need not be integers. This module can use fractional case weights in most computations. Some other modules use case weights as integer case multipliers or frequency values. This option is available only after you have defined a weight variable via the W option described below.
DF = W-1 / N-1 When the Weighted moments check box is selected, some statistics related to the moments (e.g., standard deviations and variances, skewness, kurtosis) can be based on the sum of the weight values for the weighting variable (W-1), or on the number of (unweighted) observations (N-1). The sums (and means), and sums of squares and cross products will always be based on the weighted values of the respective observations. However, in computations requiring the degrees of freedom (e.g., standard deviation, t-test, etc.), the value for the degrees of freedom can either be computed as the sum of the weight values minus one, or as the number of observations minus one. Moment statistics (except for the mean) are based on the sum of the weight values for the weighting variable when the W-1 option button is selected, and are based on the number of (unweighted) observations when the N-1 option button is selected. When the Weighted moments check box is selected, several graphics options will not be available. For more information on options for using integer case weights, see also Selecting a Weighting Variable.
