WebJan 5, 2024 · In the case of dynamic panel data model, when the number of observations for the time series is fixed at T, it is well known that the fixed effects (FE) estimator is inconsistent due to the incidental parameter problem, and so is the first-difference (FD) estimator. A nice review on the dynamic panel data model is available in Baltagi . WebConsequently, to investigate the effect of a liquid bridge on the dynamic behavior of diamond wires under support excitations, a dynamical model for the double-wire system with liquid bridge action was developed in this study based on the theory of transverse forced vibration of diamond wire under support excitations [42].
