Very well explained! Thank you! Greetings from Brazil!
Why is E(X1)=population mean?Since X1 is a particular value of X, shouldn't it mean that X1=a fixed value. Hence, shouldn't E(X1)=X1?
E(X1) is what you think the average value of X1 could be before you see it (not after).If you want to understand what it means, watch some videos about expectations. I dit not made any myself unfortunately.
Thank you so much!
In this autoregressive model X_t=(a_1+a_2 e^(-a_3 X_(t-1)^2 ))X_(t-1)+ε_t how to calculate consistency?please explain me?
