Estimation of the quadratic errors-in-variables model. (English) Zbl 0555.62056
The authors have constructed an estimator of the coefficient vector $$\beta$$ in the quadratic functional model with errors $$(e_ t,u_ t)$$ that are independent normal random variables with zero mean and known covariance matrix. The asymptotic properties of the estimator have been studied.
Small-sample behaviour of the estimator $${\hat \beta}$$ has been investigated using Monte Carlo method. The results are summarized with the help of two tables. An example from the earth sciences has been analysed.
