Cox Proportional Hazards Results - Quick Tab

Select the Quick tab to access to access the options described below:

Element Name Description
Goodness of Fit Creates 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 Creates a spreadsheet that contains the values of the log-likelihood and the parameter estimates for each individual iteration of the estimation algorithm.
Parameter estimates Creates 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 Creates a spreadsheet that contains the values of the type 3 tests for fixed effects.
Note: This option is only available when the model contains categorical effects.
Design Terms Creates a spreadsheet that contains the information for each individual column of the design matrix.
Covariance matrix Produces 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 the spreadsheet, you can specify a matrix of coefficients; the transpose of this matrix is 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 is 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 is displayed.

Residuals spreadsheet This group box contains options for displaying residuals.
Note: See Assessing the fit of the model with Residuals for additional details on the specific residual types available.
Residuals Produces a spreadsheet containing the selected residuals. Specify desired residuals by selecting the respective check boxes below this button.
Save Displays a variable selection dialog box, which is used to select variable(s) to be displayed together with the residual values in a data file for further analysis.
