Detail of computed results reported
|
Specifies the detail of computed results reported. If Minimal detail is requested, only the summary results and marginal tables for the final model will be reported; select All results to review various plots of fitted and observed frequencies; tables of observed and fitted frequencies, as well as various residual statistics, etc. can be requested as an option.
|
Input file
|
Specifies whether the input data file contains raw data (and needs to be tabulated), or contains (in the dependent variable list) frequency counts for an already computed table.
|
Automatic model
|
Select this option to have Statistica determine automatically the best fitting model for the table. See also the selections on the Automatic Model Search tab for additional options.
|
All associations models
|
Tests all marginal and partial association models; the partial association between, for example, two factors 1 and 2 (denoted by 12) is computed by comparing the fit (i.e., evaluating the Chi-square difference) of the model that includes all two-way interactions with the model that excludes the interaction between factors 1 and 2. The marginal association between, for example, two factors 1 and 2 is computed by comparing the fit of the model including all main effects (i.e., all effects of lower order than the one of interest) with the model including the interaction between factors 1 and 2.

Model to be tested
|
Specifies the model to be tested, or specify no model (leave blank) to let Statistica determine the best model (see also the Automatic Search tab). The logic of specifying models in Statistica is as follows: Refer to factors in the table by their respective numbers. Use those numbers in order to specify main effects and interactions. For example, in order to specify a model with no interactions but only main effects for each of three factors, enter 1 2 3 (separated by spaces or commas). In order to specify a model with a 2-way interaction between factors 1 and 3, and the main effect for factor 2, enter 13 2 (or 2 31; the order does not matter). Higher-order interactions are specified analogously (e.g., 124 134 15).
|
Parameter delta
|
The constant Delta (0.5 by default) is added to all frequencies in the observed table before it is submitted to the actual analysis. This is a recommended procedure when the table contains several cells with low frequencies.
|
Number of iterations
|
Specifies the maximum number of iterations to be performed during the parameter estimation.
|
Convergence criterion
|
Set the convergence criterion value (by default, 0.0001); refer to the Electronic Manual for details.
