Model Parameter Estimation

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

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 is then automatically displayed.

Option Description
Summary box Displays summary information about the current analysis.
Contract/Expand Contracts or expands 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. When expanded (the default setting), the entire Summary box will be displayed on the Model Parameter Estimation dialog.
Note: When the Summary box is contracted, the text is scrolled so that the first non-blank line is at the top.
Copy Copies 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: The copied text retains formatting information such as font, color, and other formatting parameters.
OK Displays the Regression Results dialog.
Cancel Closes the dialog without performing an analysis and return to the Regression Models for Censored Data dialog or the Proportional Hazard Model with Time-Dependent Covariates dialog.
