Dear Prof.Adve and Bill, I deeply appreciate your comments and concerns. (Please forgive my late response. I've tried some more cases to make this issue) As Prof.Adve mentioned, I need to explain exactly what my problem is, but I have no good ability that I can explain it in this plain text space. For this reason, I made a .pdf file and linked it as follows:

...hly p_n = 0.1/n . Zipf has pointed out that this type of formula, p_n = k/n, gives a rather good approximation to the word probabilities in many different languages. The formula [above] clearly can not hold indefinitely since the total probablility SUM p_n must be unity, while SUM_1^inf 0.1/n is infinite. If we assume (in the absence of any better estimate) that the formula p_n = 0.1/n holds out to the n at which the total probability is unity, and that p_n = 0 for larger n; we find that the critical n is the word rank 8,727. The entropy is then: -SUM_1^8727 p_n log_2 p_...
