Model Parameter Estimation

Click the OK button in either the Regression Models for Censored Data dialog box or the Proportional Hazard Model with Time-Dependent Covariates dialog box to display the Model Parameter Estimation dialog box.

The estimation procedure maximizes the log-likelihood of the regression model via Newton-Raphson iterations. After the best parameters have been found by STATISTICA, the iterative procedure stops and the Regression Results dialog box is then automatically displayed.

Summary box. The Summary box displays summary information about the current analysis.

Copy button. Click the Copy button to copy either the selected text (if text has been selected) in the Summary box or all of the text (if no text has been selected) to the Clipboard. Note that the copied text retains formatting information (such as font, color, etc.).

Contract/Expand button. Click the Contract/Expand button to contract or expand the Summary box. When contracted, you can see only one line of the Summary box text and can scroll through the text using a scroll bar. Note that when contracted the text is scrolled so that the first non-blank line is at the top. When expanded (the default setting), the entire Summary box will be displayed on the Model Parameter Estimation dialog box.

OK. Click the OK button to display the Regression Results dialog box.

Cancel. Click the Cancel button to close the dialog without performing an analysis and return to the Regression Models for Censored Data dialog box or the Proportional Hazard Model with Time-Dependent Covariates dialog box.
