# Life Tables Options

You can control various aspects of your Life Tables analysis.

**Life table(s).** To suppress
the display of life tables in the output, deselect Life table(s).

**Plot.** Allows you to request plots of the survival functions. If you have
defined factor variable(s), plots are generated for each subgroup
defined by the factor variable(s). Available plots are survival, log
survival, hazard, density, and one minus survival.

- Survival. Displays the cumulative survival function on a linear scale.
- Log survival. Displays the cumulative survival function on a logarithmic scale.
- Hazard. Displays the cumulative hazard function on a linear scale.
- Density. Displays the density function.
- One minus survival. Plots one-minus the survival function on a linear scale.

**Compare Levels
of First Factor.** If you have a first-order control variable,
you can select one of the alternatives in this group to perform the
Wilcoxon (Gehan) test, which compares the survival of subgroups. Tests
are performed on the first-order factor. If you have defined a second-order
factor, tests are performed for each level of the second-order variable.
