The book that I am using Project Management Process Methodologies, and economics 2nd edition.

#### Solution Preview

Stochastic Approach - Advantages - provides the ability to derive standard errors for the estimates of purchasing power parities. (utilizes ranges of values - probability distributions)
Disadvantages - The perceived costs are not independent
Example:

Time
A notable special case is where the time is a discrete set, for example the nonnegative integers {0, 1, 2, 3, ...}. Another important special case is .
Stochastic processes may be defined in higher dimensions by attaching a multivariate random ...
