Hi,
I want to estimate bootstrap CI of parameters estimated by a logistic regression.
The event i'm studing is quite rare (2%)and so in many bootstrap replications (96/100) paramenters could not be estimated.

I increased the number of replication (5000)to obtain 300 completed replications, but i'm not sure it's the right method.
Does somebody know if there are other methods?

Thank you
