WebA sample statistic that estimates a population parameter. The value of the estimator is referred to as a point estimate. There are several different types of estimators. If the expected value of the estimator equals the population parameter, the estimator is an unbiased estimator. 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 …
