Density for parametric survival distribution
DESCRIPTION:
Density for parametric survival distribution.
USAGE:
f.phis(z, distribution)
REQUIRED ARGUMENTS:
- z
-
time at which density is desired (may be negative).
- distribution
-
the failure distribution. This may be one of "extreme", "gaussian",
or "logistic"
VALUE:
The density of the distribution at the time z assuming link = "identity".
