    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.
