چکیده
This paper constitutes a serious attempt to develop a new inference method for structural models with latent variables. In addition to tackling some difficult econometric issues, it is carefully executed with thoughtful discussions on many detailed issues. Overall, I see this article as a nice addition to the literature that focuses on the development of efficient and feasible econometric methods for structural models. My comments will revolve around one very basic question: as a practicing econometrician, under what situation will I choose the proposed latent backfitting method over existing approaches?

New adaptive interpolation schemes for efficient meshbased motion estimation
Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

A recent paper by Grutters et al makes the case for early health economic modeling in the development of health technologies. A number of examples of the value of early modeling are given, with analyses being performed at different stages in the development of several non-drug health technologies. This commentary acknowledges the contribution of the paper by Grutters et...
متن کاملPerfect Tracking of Supercavitating Non-minimum Phase Vehicles Using a New Robust and Adaptive Parameter-optimal Iterative Learning Control
In this manuscript, a new method is proposed to provide a perfect tracking of the supercavitation system based on a new two-state model. The tracking of the pitch rate and angle of attack for fin and cavitator input is of the aim. The pitch rate of the supercavitation with respect to fin angle is found as a non-minimum phase behavior. This effect reduces the speed of command pitch rate. Control...
متن کاملApplication of Recursive Least Squares to Efficient Blunder Detection in Linear Models
In many geodetic applications a large number of observations are being measured to estimate the unknown parameters. The unbiasedness property of the estimated parameters is only ensured if there is no bias (e.g. systematic effect) or falsifying observations, which are also known as outliers. One of the most important steps towards obtaining a coherent analysis for the parameter estimation is th...
