Query: Asymptotic normality of element-wise weighted total least squares
  estimator in a multivariate errors-in-variables model   A multivariable measurement error model $AX \approx B$ is considered. Here
$A$ and $B$ are input and output matrices of measurements and $X$ is a
rectangular matrix of fixed size to be estimated. The errors in $[A,B]$ are
row-wise independent, but within each row the errors may be correlated. Some of
the columns are observed without errors and the error covariance matrices may
differ from row to row. The total covariance structure of the errors is known
up to a scalar factor. The fully weighted total least squares estimator of $X$
is studied. We give conditions for asymptotic normality of the estimator, as
the number of rows in $A$ is increasing. We provide that the covariance
structure of the limiting Gaussian random matrix is nonsingular.
