Regression Results - Advanced Tab
Select the Advanced tab of the Regression Results dialog box to access options to view the parameter estimates, covariances, and correlations, the results of the stratified analysis, and the means and standard deviations.
| Option | Description |
|---|---|
| Summary: Parameter estimates | Displays a spreadsheet with parameter estimates, their standard errors, the ratio of the parameter estimates divided by their standard errors (under the heading t-value), 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.
|
| Parameter covariances & correlations | Displays two spreadsheets, one with the variance/covariance matrix of the parameter estimates and one with the correlation matrix. |
| 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 available only if a stratified analysis (analysis by groups) is 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 is 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.
|
| Means & standard deviations | Displays a spreadsheet with the means and standard deviations for the survival times and the independent variables (covariates). |
| Expressions with covariates | Creates a spreadsheet containing the expressions for time-dependent covariates which you specified in the Proportional Hazard Model with Time-Dependent Covariates dialog box. |
