I am trying to match survival curves in JMP survival platform to the PROC LIFETEST.  The estimates I get for the survival functions using the KM method are not matching.  Am I looking at the wrong thing?  the format of the data is the same for both (see below) The dataset I am using is from Survival Analysis using SAS , Paul Allison, output 2.1 Myelomatosis Data.  Also Below is the two different sets of estimates.  It is the survival columns I am comparing.  I must be doing something wrong?  any insight appreciated!

This is the sorted data set -- easier to look a (status=1 ==> failure,  status=0 ==> censored)
