| Conf. Level
|
Enter the value to be used for constructing confidence limits for the parameter estimates and the risk or hazard ratio.
The default value, 95% confidence limits is constructed.
|
| Summary: Parameter estimates
|
Displays a spreadsheet with parameter estimates, their standard errors, confidence intervals, the ratio of the parameter estimates divided by their standard errors (under the heading t-value), the exponentiation of the parameter estimate (also called the risk ratio or hazard ratio), the confidence interval for the risk ratio, and the Wald statistic (which for large samples has a Chi-square distribution under the null hypothesis that the coefficient is equal to 0).
Note: The standard errors (and t-values) are computed from the second order partial derivatives of the log-likelihood function, resulting in asymptotic standard errors (and t-values) for the parameters.

| Stratified analysis
|
Displays a spreadsheet with the results of the stratified analysis; specifically, the spreadsheet shows the sum of the log-likelihoods of the model, fitted within each group, and the log-likelihood of the model fitted to all observations combined. In order to examine the parameter estimates for a particular group, specify the appropriate case selection conditions (that is, select only cases belonging to the group of interest), and then fit the respective model in the usual manner.
Note: Stratified analysis is only available if a stratified analysis (analysis by groups) was requested on the
Regression Models for Censored Data dialog box - Quick tab or the
Proportional Hazard Model with Time-Dependent Covariates dialog box - Quick tab (that is, a grouping variable has been selected) and if the
Equal coefficients, different baseline h0 (in stratified analysis)
check box on the
Regression Models for Censored Data dialog box - Options tab is not selected.
