A trend formula for the variance

[Ad VanderVen]

TL;DR

In a paper published in the JOURNAL OF MATHEMATICAL PSYCHOLOGY 39, 265-274 (1995), formulas are provided on page 272 for the expectation of a random variable as dependent on n (formulas 28 and 29). What do these formulas look like for the variance?

In a paper published in the JOURNAL OF MATHEMATICAL PSYCHOLOGY 39, 265-274 (1995), formulas are provided on page 272 for the expectation E(T_n) of a random variable T as dependent on n (formulas 28 and 29). Now I would like to know what these formulas look like for the variance i.e. Var(T_n).

Ah, this one again! Have you read the paragraph below eqn 21? Are you prepared to put in the "little more effort"? (Might be more than a little, in my opinion!) The result is "rather complicated". Do you really need it? Is eqn 24 not good enough?

Yes, I really need Var(T_n).
