Aggregation techniques

Main article: Technical overview of the ratings system

Aggregation refers to the way we combine the opinions of others to obtain a final value of the opinion. A poll which takes the sum of each person's candidate preference in an election and then calculates the percentage for each candidate is an aggregation technique.

A number of aggregation techniques are possible. A few are listed here:

1. Bayes' equation with a simple example of its use.
2. Simple averaging
3. Trust weighted averaging
4. An analysis of these methods and simple weighted averaging
5. Trust-weighted histograms
6. Binned and continuous distributions
7. Population distributions, privacy, and graphical output
