%X There are a number of papers discussing the comparison of the squared residuals of the Total Least Squares(TLS) and the Least Squares(LS) problems. In this paper, the weighted squared residuals of the TLS and the LS problems are compared. Bounds of difference between the weighted squared residuals of the TLS, modified LS, and ordinary LS solutions are derived. Thus the existing related results are expanded.
