Life Distribution - How to Enable Left censor?

[#1]

Hi,

I am working on the life distribution analysis, and I can only enable the data to right censor using censor column (censor code=1).

But I had some data needed to be "left-censored" but I don't know how to enable left censor.

Thanks in advanced!

I think this is how you do it:

1. Organise the data with separate columns for start and end times.  If the end time is missing it denotes right-censored data, if the start time is missing it denotes left-censored data.

2. Launch the Life Distribution platform and assign both the start and end columns as the "Y,Time to Event" role.

@David_Burnham is correct. Using two time-to-event columns also is how one would specify interval censoring. See this documentation page for an example.
