`X`	The design (covariate) matrix.
`Y`	A survival object, the response.
`cuts`	Specifies the points in time where the hazard function jumps. If omitted, an exponential model is fitted.
`strata`	A stratum variable.
`offset`	Offset.
`init`	Initial regression parameter values.
`control`	Controls convergence and output.
