i have one for loop,in which i am dealing with time series & arima function,
while iterating at some stage there is a error, like
Error in arima(x, c(p, 0, q)) : non-stationary AR part from CSS
i want to know at which step this error occurred & print that iterating
number
e.g.
x<-c(1:10)
for (i in 1:5 ){
z<-arima(x[i])
print(z)
}
if error occurred in arima function at i=3 step, it should report & execute
complete loop until i=5
