Thank you to Jonathon and patc3,
Yes, I can find there is not line for conf.type to specify the analysis method. I hope I can use other methods for survival analysis.

Regards,

Which analytical method is used for the confidence intervals for the median overall survival in Death Watch? In my case, the CI is not identical with other results which utilized Greenwood formulae.
And please let me know the method is used for the confidence intervals for 1, 3, 5years survival rate.

Thanks, Jonathon. My categorical variable is text type, and JAMOVI seems not to allow use text type covariate. How can I use text type variable as covariate?

Can I use some categorical variables as covariate while doing ANCOVA in JAMOVI?
