Abstract

In the above article [1], a wording ambiguity appears in Proposition 4 regarding the description of the missing at random (MAR) mechanism. The published sentence states that the probability of observing the kth sample depends on the realized measurement value. This wording may be interpreted as dependence on the current unobserved value y[tk], which could suggest a missing not at random (MNAR) mechanism. The intended MAR mechanism is that the observation probability for the kth sample depends only on previously observed measurement information, such as y[tk-1], and not on the current unobserved value y[tk]. Therefore, the corrected wording clarifies that the selection probability is based on past observed information. For k = 1, no previous sample exists, so w1 is initialized using a neutral average-magnitude value. This correction is purely a clarification of the missingness mechanism. It does not change the mathematical derivation, simulation procedure, numerical results, figures, tables, or conclusions of the article.
