Enter the level of confidence for the confidence intervals for the coefficients and the fitted values. If you use the logit link function, this confidence level is also the confidence level for the confidence intervals for the odds ratios.
Usually, a confidence level of 95% works well. A 95% confidence level indicates that, if you took 100 random samples from the population, the confidence intervals for approximately 95 of the samples would contain the parameter that the interval estimates. For a given set of data, a lower confidence level produces a narrower interval, and a higher confidence level produces a wider interval.
To display the confidence intervals for the coefficients and the fitted values, you must go to the Results sub-dialog box, and from Display of
results, select Expanded tables.
