Workspace Node: Cox Proportional Hazards - Results - Quick Tab

In the Cox Proportional Hazards node dialog box, under the Results heading, select the Quick tab to access the following options.

Element Name Description
Goodness of Fit Select this check box to create a spreadsheet that contains the following summary statistics: -2LogL, AIC, SBC, R2, Score, Likelihood Ratio, and Wald statistic, which describe the overall fit of the model.
Iteration history Select this check box to create a spreadsheet that contains the values of the log-likelihood and the parameter estimates for each individual iteration of the estimation algorithm.
Parameter estimates Select this check box to create a spreadsheet that contains the values of the parameter estimates, standard errors of the parameter estimates, chi-square statistic, p-value associated with the chi-square statistic, confidence intervals, hazard ratios, and confidence intervals for hazard ratios.
Type 3 Tests Select this check box to create a spreadsheet that contains the values of the type 3 tests for fixed effects. Note that this option is only available when the model contains categorical effects.
Design Terms Select this check box to create a spreadsheet that contains the information for each individual column of the design matrix.
Covariance matrix Select this check box to produce the covariance matrix.
Estimate If you have not already specified a matrix of coefficients (by clicking the button), click the Estimate button to display the Specify effect to estimate dialog box. In that spreadsheet you can specify a matrix of coefficients; the transpose of this matrix will be post-multiplied by the matrix of parameter estimates to yield a linear combination of parameter estimates that specifies a hypothesis (or simultaneous set of hypotheses) that will be tested. To use the common notation, STATISTICA expects you to specify a matrix of estimable functions L' (L transposed; L is assumed to be a row matrix), specifically, the statistical significance tests pertain to the hypothesis:

Lb = 0

where L is the transposed matrix of coefficients specified in the Specify Effect to Estimate dialog box), and b is the matrix of parameter estimates.

The user-defined L matrices are tested for estimability as well as redundancy (i.e., if a column in L' is a linear function of other columns), and if any of these conditions occur, an error message will be displayed.

Residuals spreadsheet This group box contains options for displaying residuals. See Assessing the fit of the model with Residuals for additional details on the specific residual types available.
Residuals Select this check box to produce a spreadsheet containing the selected residuals. Specify desired residuals by selecting the respective check boxes below this button.

Options / C / W. See Common Options.

OK Click this button to accept all the specifications made in the dialog box and to close it. The analysis results are placed in the Reporting Documents node after running (updating) the project.
