COMPUTING MEDIAN UNBIASED ESTIMATES IN MACROECONOmTRIC MODELS
A stochastic simulation procedure is proposed in this papa for obtaining median unbiased (Mu) estimates in macroeconometric models. MU estimates are computed for lagged dependent variable (LDV) coefficients in 18 equations of a macroeconometric model. The 2SLS bias for a coefficient, defined as the difference between the 2SLS estimate and the MU estimate, is on average smaller in absolute value...
متن کاملEffects of electrode location on myoelectric conduction velocity and median frequency estimates.
The effect of surface electrode location on the estimates of the median frequency and conduction velocity of the myoelectric signal was investigated. The locations were identified with respect to the innervation zone and the tendonous portion of the tibialis anterior muscle. Considerable modifications in the median frequency and conduction velocity parameters were noted. The highest values of t...
متن کاملMultiple Tail Median and Bootstrap Techniques for Conservative Reliability Estimates in Design Optimization
Reliability based design with expensive computer models becomes computationally prohibitive when reliability is estimated by sampling methods. While designing for high reliability with few samples, techniques like tail models are widely used to extrapolate reliability levels from observed levels to unobserved levels. One such approach, the multiple tail median approach uses two classical tail m...
متن کاملOn Median Graphs and Median Grid Graphs on Median Graphs and Median Grid Graphs
Let e be an edge of a median graph G which is contained in exactly one 4-cycle. Then it is proved that G n e is a median graph. The converse holds as well provided that e is not contained is a subgraph isomorphic to the 3-cube minus a vertex. These results are used to give several characterizations of median grid graphs. (Grid graphs are subgraphs of complete grids, i.e. of the Cartesian produc...
متن کاملCalculation of statistic estimates of kinetic parameters from substrate uncompetitive inhibition equation using the median method
We provide initial rate data from enzymatic reaction experiments and tis processing to estimate the kinetic parameters from the substrate uncompetitive inhibition equation using the median method published by Eisenthal and Cornish-Bowden (Cornish-Bowden and Eisenthal, 1974; Eisenthal and Cornish-Bowden, 1974). The method was denominated the direct linear plot and consists in the calculation of ...
