HADES Updates

What's New in release 1.1?

1) The density estimation is changed to the following two methods:
method_den = 1 density calculated from the smoothed hazard function h(t) directly:

h(t)*exp(-\int_0^t h(u)du) (default, no smoothing needed).

method_den = 2 density calculated from local linear smoothing of the derivative

CdS(t)/dt, where S(t)=exp(-\int_0^t h(u)du)

is the survival function and h(t) is the smoothed hazard function.

2). The censoring indicator is changed as follows:

censor(i) = 1 ==> x(i) is right censored liftime
censor(i) = 0 ==> x(i) is uncensored liftime

3). The default kernel is changed from 'epan' to 'gauss'.
