Life Distribution - Compare Groups Report Options

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.

See Local Data Filter, Redo Menus, and Save Script Menus in Using JMP for more information about the following options:

Local Data Filter

Shows or hides the local data filter that enables you to filter the data used in a specific report.

Redo

Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.

Save Script

Contains options that enable you to save a script that reproduces the report to several destinations.

Save By-Group Script

Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.

Estimate Probability Report

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).
