Export (Complex Samples Cox Regression)
Export model as IBM® SPSS® Statistics data. Writes a dataset in IBM SPSS Statistics format containing the parameter correlation or covariance matrix with parameter estimates, standard errors, significance values, and degrees of freedom. The order of variables in the matrix file is as follows.
- rowtype_. Takes values (and value labels), COV (Covariances), CORR (Correlations), EST (Parameter estimates), SE (Standard errors), SIG (Significance levels), and DF (Sampling design degrees of freedom). There is a separate case with row type COV (or CORR) for each model parameter, plus a separate case for each of the other row types.
- varname_. Takes values P1, P2, ..., corresponding to an ordered list of all model parameters, for row types COV or CORR, with value labels corresponding to the parameter strings shown in the parameter estimates table. The cells are blank for other row types.
- P1, P2, ... These variables correspond to an ordered list of all model parameters, with variable labels corresponding to the parameter strings shown in the parameter estimates table, and take values according to the row type. For redundant parameters, all covariances are set to zero; correlations are set to the system-missing value; all parameter estimates are set at zero; and all standard errors, significance levels, and residual degrees of freedom are set to the system-missing value.
Note: This file is not immediately usable for further analyses in other procedures that read a matrix file unless those procedures accept all the row types exported here.
Export survival function as IBM SPSS Statistics data. Writes a dataset in IBM SPSS Statistics format containing the survival function; standard error of the survival function; upper and lower bounds of the confidence interval of the survival function; and the cumulative hazards function for each failure or event time, evaluated at the baseline and at the predictor patterns specified on the Plot tab. The order of variables in the matrix file is as follows.
- Baseline strata variable. Separate survival tables are produced for each value of the strata variable.
- Survival time variable. The event time; a separate case is created for each unique event time.
- Sur_0, LCL_Sur_0, UCL_Sur_0. Baseline survival function and the upper and lower bounds of its confidence interval.
- Sur_R, LCL_Sur_R, UCL_Sur_R. Survival function evaluated at the "reference" pattern (see the pattern values table in the output) and the upper and lower bounds of its confidence interval.
- Sur_#.#, LCL_Sur_#.#, UCL_Sur_#.#, … Survival function evaluated at each of the predictor patterns specified on the Plots tab and the upper and lower bounds of their confidence intervals. See the pattern values table in the output to match patterns with the number #.#.
- Haz_0, LCL_Haz_0, UCL_Haz_0. Baseline cumulative hazard function and the upper and lower bounds of its confidence interval.
- Haz_R, LCL_Haz_R, UCL_Haz_R. Cumulative hazard function evaluated at the "reference" pattern (see the pattern values table in the output) and the upper and lower bounds of its confidence interval.
- Haz_#.#, LCL_Haz_#.#, UCL_Haz_#.#, … Cumulative hazard function evaluated at each of the predictor patterns specified on the Plots tab and the upper and lower bounds of their confidence intervals. See the pattern values table in the output to match patterns with the number #.#.
Export model as XML. Saves all information needed to predict the survival function, including parameter estimates and the baseline survival function, in XML (PMML) format. You can use this model file to apply the model information to other data files for scoring purposes. See the topic Scoring Wizard for more information.
How To Export Model Information
This feature requires the Complex Samples option.
- From the menus choose:
- Select a plan file. Optionally, select a custom joint probabilities file and then click Continue.
- Click the Export tab.
