%description
Function for growing survival trees ensemble ('Naz Gul', 'Nosheen Faiz',
'Dan Brawn', 'Rafal Kulakowski', 'Zardad Khan', and 'Berthold Lausen'
(2020) <arXiv:2005.09043>) is given. The trees are grown by the method of
random survival forest ('Marvin Wright', 'Andreas Ziegler' (2017)
<doi:10.18637/jss.v077.i01>). The survival trees grown are assessed for
both individual and collective performances. The ensemble can give
promising results on fewer survival trees selected in the final ensemble.
