Program SURVIV User's Manual Version 1.2

Program SURVIV (a stand alone program) is used to estimate survival rates from user specified cell
probability functions. The program reads the user specified algebraic expressions and constructs a
FORTRAN 77 subroutine that calculates the log-likelihood function. Numerical optimization is then
used to estimate the unknown parameters. Currently the program is available for CDC-NOS, VAXVMS,
UNIX, PC-DOS, and MS-DOS operating systems. The NOS version is written in single
precision, while the VMS, UNIX, and DOS versions are written in double precision.
