which of following is a random variable for the forecasting period how can i simulate the probability of observing 1 what is the random variable x_t how to use arima model to predict forecast? x_t is used to predict a rare event what is the value of x_t in arima simulation what is the average of the forecasting intervals? what is the random variable in forecasting what is x_t? how to get the forecast intervals why are the simulated value of xt over the forecasting period how can i simulate x_t over time what is the probability of an observation being one of a rare event? how to find a random variable in a forecast model what is the forecasting variance can an indicator random number be used in a simulation what is the value of the indicator in the forecasting period called x_t is an indicator random variable a function of which what is x_t how to find the probability for rare event in the x_t$
