**What is a 10-year Rainstorm? terms such as â€œ10-year event**

For these estimates, hydrologists use Return Periods. Simply stated, a return period is an estimate of how long it will be between rainfall events of a given magnitude. For example, the return period for a 3-hour rainfall total of 4.25 inches in Oklahoma City is 25 years. This means that, on the average, a 4.25 inch rainfall over three hours occurs in Oklahoma City once every 25 years.... Also, you may need to cumulate the daily abnormal returns over several days (this period is called event window) in order to capture the entire effect of your event. Best 1 Recommendation

The Data The data are monthly percentage returns for the period July 1926 to December 2013 (T = 1050) on 25... For example, specify n = 3 in the processing option 10b to use the most recent three periods as the basis for the projection into the next time period. The system will automatically assign the weights to the historical data that decline linearly and sum to 1.00. For example, when n = 3, the system will assign weights of 0.5, 0.3333, and 0.1, with the most recent data receiving the greatest weight.

### What I would like to do now is calculate a return for holding my asset for 20 days (i.e. buying it at the first day and selling it at day 20), and do this for each day. So I would like to calculate this:

- While one-period returns may be normally distributed, this will generally not be the case for the value of a portfolio many periods hence, due to the effects of compounding. If $1 is invested initially, the value will be (1+r1) at the end of period 1, where r1 is the rate of return in the first
- Also, you may need to cumulate the daily abnormal returns over several days (this period is called event window) in order to capture the entire effect of your event. Best 1 Recommendation
- The easiest way to calculate days between dates in Excel is by subtracting one date from another: Newer date - Older date. For example, to find out how many days are between dates in cells A2 and B2, you use this formula: =B2 - A2. Where A2 is an earlier date, and B2 is a later date. The result is an integer that represents no. of days between two dates: How this formula works. As you probably
