 # Empirical probability

## Empirical probability,

### Definition of Empirical probability:

1. Empirical probability uses the number of occurrences of an outcome within a sample set as a basis for determining the probability of that outcome. The number of times "event X" happens out of 100 trials will be the probability of event X happening. An empirical probability is closely related to the relative frequency of an event.

2. A statistical model whereby the likelihood of an event happening is supported by market data. The calculation is expressed as a ratio between the number of times an event occurs to the number of possible times it could occur. Also called posterior probability.

3. In order for a theory to be proved or disproved, empirical evidence must be collected. An empirical study will be performed using actual market data. For example, many empirical studies have been conducted on the capital asset pricing model (CAPM), and the results are slightly mixed.
