Automatic Inference for Infinite Order Vector Autoregressions
Vector Autoregressions instrument
2015/9/22
Infinite order vector autoregressive (VAR) models have been used in a number of applications
ranging from spectral density estimation, impulse response analysis, tests for cointegration and uni...
Estimation with Weak Instruments: Accuracy of Higher Order Bias and MSE Approximations
weak instruments higher order expansions
2015/9/22
In this paper we consider parameter estimation in a linear simultaneous equations model. It
is well known that two stage least squares (2SLS) estimators may perform poorly when the
instruments are w...
Investigation of Thirty Meter Telescope Wavefront Maintenance Using Low Order Shack-Hartmann Wavefront Sensors to Correct for Thermally Induced Misalignments
Wavefront Sensing and Control Active Optics On-Instrument Wavefront Sensor
2015/5/13
We evaluate how well the performance of the Thirty Meter Telescope (TMT) can be maintained against thermally
induced errors during a night of observation. We first demonstrate that using look-u...
