Many of the options in the Compare Groups red triangle menu can also be found in the Life Distribution red triangle menu. See Life Distribution Report Options.
However, the following options are specific to Compare Groups:
Show Quantile Functions
Shows or hides the Compare Quantile report. Select a distribution. For each group, a curve is plotted showing the estimated quantiles for the time variable. Confidence bands are displayed. A legend is shown to the right of the plot. Only one distribution can be specified at a time.
Show Hazard Functions
Shows or hides the Compare Hazard report. Select a distribution. For each group, a curve is plotted showing the hazard function. Confidence bands are displayed. A legend is shown to the right of the plot. Only one distribution can be specified at a time.
Show Density Functions
Shows or hides the Compare Density report. Select a distribution. For each group, the density function and confidence bands are displayed. A legend is shown to the right of the plot. Only one distribution can be specified at a time.
Estimate Probability
Adds an Estimate Probability report corresponding to the most recently selected distribution under Compare Distribution. Enter a value for the Time to Event variable in the text box and press Enter. To add a Time to Event value, click the plus sign. To remove the most recent value, click the minus sign. See Estimate Probability Report.
Estimate Quantile
(Appears only if Compare Quantile is selected.) Adds an Estimate Quantile report corresponding to the most recently selected distribution under Compare Quantile. Enter a value for the probability of interest in the text box and press Enter. To add a Prob value, click the plus sign. To remove the most recent value, click the minus sign. For each group and probability value, the Time to Event quantile and 95% Wald and Likelihood confidence intervals are shown.
Note: The Local Data Filter option is not available in the Compare Groups red triangle menu.
For each group and Time to Event value, this report provides the following:
Midpoint Estimate
Midpoint-adjusted Kaplan-Meier estimate of failure by the specified time.
Lower 95%, Upper 95%
Pointwise 95% confidence intervals for the probability of failure by the specified time.
Simultaneous Lower 95% (Nair), Simultaneous Upper 95% (Nair)
Simultaneous 95% confidence intervals for the probability of failure by the specified time. See Nair (1984) and Meeker and Escobar (1998).
Survival Probability
Midpoint-adjusted estimate of survival beyond the specified time.
Survival Probability Lower 95%, Upper 95%
Pointwise 95% confidence intervals for the probability of survival beyond the specified time.
Survival Probability Simultaneous Lower 95% (Nair), Simultaneous Upper 95% (Nair)
Simultaneous 95% confidence intervals for the probability of survival beyond the specified time. See Nair (1984) and Meeker and Escobar (1998).
