Dear Enzo,
Thank you for you precious help, I tried typing -adjust- in the -strs-
options but got "option adjust not allowed" as a reply from stata... Is it
not implemented with the available -strs- or has it got a syntax I should
know?
Do I need to contact Paul Dickman to get permission to use this option?
I really need this option to be able to use -strs- which I find extremely
useful and practical otherwise.
Thank you
Val�rie

Subject: Re: st: parameterising strs to avoid cumulative relative survival
increase
Yes, there is.
In -strs- the undocumented option -adjust-
allowed to avoid the increase of the realtive survival.
Paul Dickman, the main author of the macro, is
contrary to the use of this option for several
reasons and so the -adjust- option has been removed.
In principle I agree with Paul Dickman even if I
believe a macro is fundamentally a tool and the
user has the responsibility to clearly document how they have been obtained.
I would suggest to write directly to Paul Dickman
hoping that he replies (p < 1/1000000) and he
reconsiders the opportunity to introduce again -adjust-
Best wishes.
