ETAS Model Information for Error Diagram Code #3

What does the confidence interval outputted by the ETAS code mean? It is returning one number, correct?

Also, we are working on it now, but does anyone understand what this means?

etas.CI <- function(time,t.events,mag.events,m0,mu,K,alpha,c,p){ mu+sum(K10^(alpha(mag.events-m0))/(time-t.events+c)^p) }

From what I understand, ETAS is a combination of space and time relationships so there has to be a range of what time an event can occur per location. The etas.CI function is demonstrating the time range between values an earthquake is predicted to occur at a specified location. This also goes back to what Chris was discussing in class a week or so ago.

So the etas.CI function returns the time range? Like how long the alarm is on for?
