Survival Analysis when "time to event" is category/interval
Mar 12, 2024 06:03 PM(3882 表示)
Hi there
Does JMP have a module/script to run a Survival analysis when we group the event times into intervals (as en example, time to event split into a category, 0 - 5 days, 6 -10 days, 11-15 days etc...).
Based on the limited description you provided, it is difficult to answer that question, but you intervals are in Y, not X, so segmenting the model does not seem reasonable to me.
I have as time to event variable (continuous variable which is observed each day) and a censor variable pre-defined. Curious to know if i categories the time to event variable how does oen fit a COX PH?
Yes, JMP does offer capabilities for conducting Survival analysis, including scenarios where event times are grouped into intervals. You can achieve this using the "Interval Censoring" option in the Fit Life by X platform. This allows you to specify intervals for the event times and perform Survival analysis accordingly. Thanks for sharing https://community.jmp.com/t5/Discussions/Survival-Analysis-when-quot-time-to-event-quot-is-category/...view
Given that I’m interested in estimating a hazard rate per time ‘interval ‘is this possible?
So assume I have pre-specified time to event intervals, as an example 0 to 5 days, for instance and also have a continuous time to event variable - my main interest is estimating a hazard ratio for the interval (0 to 5 days) for instance.
