Nine return-period curves of 50-year samples from a theoretical 1000-year record (base line) The strict notion of return period actually has a meaning only when it concerns a time-dependent phenomenon, like point rainfall. The return period then corresponds to the expected waiting time until the exceedance occurs again.
The Ohlson O-score for predicting bankruptcy is a multi-factor financial formula postulated in 1980 by Dr. James Ohlson of the New York University Stern Accounting Department as an alternative to the Altman Z-score for predicting financial distress.
The theoretical return period between occurrences is the inverse of the average frequency of occurrence. For example, a 10-year flood has a 1/10 = 0.1 or 10% chance of being exceeded in any one year and a 50-year flood has a 0.02 or 2% chance of being exceeded in any one year.

A base effect [11] relates to inflation when in the corresponding period of the previous year. If the inflation rate was too low in the corresponding period of the previous year, even a smaller rise in the Price Index will arithmetically give a high rate of inflation now. On the other hand, if the price index had risen at a high rate in the ...
There are four aspects for alternative measures of REER which are (a) using end-of-period or period averages of the nominal exchange rate. (b) choosing price indexes. (c) in obtaining the real effective exchange rates, deciding upon the number of trading partners in calculating the weights. (d) deciding upon the formula to use in aggregation.
Note: In this algorithm January and February are counted as months 13 and 14 of the previous year. E.g. if it is 2 February 2010 (02/02/2010 in DD/MM/YYYY), the algorithm counts the date as the second day of the fourteenth month of 2009 (02/14/2009 in DD/MM/YYYY format) So the adjusted year above is:
