    [JMP 8] Performing a Kaplan Meier Survival Analysis




    Hi all,

    I would like to perform a Kaplan Meier curve with JMP 8.

    It seems easy but I have a problem:
    My sample is composed of people which die after a certain amount of time. However some people will not be dead at the end.
    When I enter my data in my table, I input the time necessary for them to die. Therefore I have missing value in my table for the one who do not die.

    When I perform a survival analysis, JMP will only consider the people with a time to event...and therefore do not include the others which for me seems to be important too.

    Can some1 help me with this matter pls?

    Thank your very much !

    "However some people will not be dead at the end."
    So these people are right-censored observations?
    You should have their censored time as well (at the end of the experiment)?

    thank you for your answer! I was finally able to do it.

    Indeed, I was missing the censored part of my data and that is why it did not work properly !!!

    Thank you so much!

    Can you also help me for this:
    I would like to test the impact of several parameters against the survival curve.
    For character nominal value, I have used the survival analysis and included my parameter to test in the grouping value. It seems to work well when I have only 2 groups.
    However when the parameter to test have several category, I only have a global statistical value and still I don't know which is significant compare to what...

    Have you some ideas?

    Also when I want to test a continuous numeric value to this survival curve...I don't know which test I have to do...

    Any help is welcome.
