Change in the risk value in a Kaplan-Meier analysis

Hello,

 

Is it possible, for a Kaplan Meier analysis with a log-rank test, to change the value of the risk α? I would need to do the analysis with an α = 5% / N, where N represents the number of samples to compare?

 

Thank you.

Re: Changement de la valeur du risque dans une analyse de Kaplan-Meier

You can only change the alpha level when fitting one of the parametric models. This will not change the plot, but the estimate of the parameter. To see the estimate and the corresponding confidence interval press the shift key and select exponential fit. A dialog will open allowing you to enter the alpha level as in the bellow example picture.
