WebAug 17, 2024 · Answers (1) There is no multi-output recursive estimator available today in System Identification Toolbox; this is a limitation. What you need is a true multi-output estimator (e.g., armax, or state-space form), which doesn't exist right now. Workaround: try some post-processing manipulations like converting to state-space (using the Model … An "estimator" or "point estimate" is a statistic (that is, a function of the data) that is used to infer the value of an unknown parameter in a statistical model. A common way of phrasing it is "the estimator is the method selected to obtain an estimate of an unknown parameter". The parameter being estimated is sometimes called the estimand. It can be either finite-dimensional (in parametric and semi-parametric models), or infinite-dimensional (semi-parametric and non-parametric models). …
