Business Statistics Made Easy in SAS

Step 4: Include Scope

Often these types of calculations are on a per-period, per-person (or other unit) basis. If so, estimate the amount of total time and number of units involved. For example, if you have a statistical effect that extends for 10 time periods over 300 people, your scope may be multiplied – on a simple basis – by 3,000. This step can be complex in reality, and it requires careful thought (for instance, do the effects decay over time?).
