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.
