Hello all. I have a two statements. One says
-1/T Sum X_t - a converges in probability to 0 as T approaches infinity (sum from t=1 to T)
The other:
-1/g(T) Sum X_t -a converges in probability to 0 as g(T) approaches infinity (sum from t=1 to g(T)) for g: N to N: g(T) approaches infinity as T approaches infinity.
Why are those two statements equivalent for random sequence X_t?
