Study Notes
Estimation Theory
- Branch of statistics that deals with estimating the values of parameters based on measured empirical data with a random component.
Role of Estimator
- Attempts to approximate the unknown parameter value from the data.
Approaches in Estimation Theory
- Two general approaches: Probabilistic Approach and Set-Membership Approach.
Probabilistic Approach
- Probability distribution of the measured data depends on the unknown parameter vector.
Set-Membership Approach
- Assumes the measured data vector belongs to a set which depends on the parameter vector.
Applications of Estimation Theory
- Can be applied in scenarios where a parameter needs to be estimated from noisy data, such as signal processing or image processing.
Role of Parameters
- The parameter sought represents the unknown quantity of interest.
- The value of the parameters affects the behavior of the system or process.
Goal of an Estimator
- The main goal of an estimator is to produce an estimate that is close to the true parameter value.
Probabilistic Approach Assumptions
- Assumes that the measured data is a realization of a random variable.
