Finite sample properties of estimators of spatial autoregressive models with autoregressive disturbances
Spatial autoregressive models ordinary least squares two-stage least squares maximum likelihood finite sample distribution
2015/9/24
The article investigates the finite sample properties of estimators for spatial autoregressive models where the disturbance terms may follow a spatial autoregressive process. In particular we investig...
Asymptotic Properties of Multiperiod Control Rules in the Linear Regression Model
Asymptotic Properties Multiperiod Control Rules
2015/8/5
This is the value of the control rule which would be used if one treated ,d as
known with certainty and equal to the least squares estimate. We call this rule
the least squares certainty equivalence...
Some Experimental Results on the Statistical Properties of Least Squares Estimates in Control Problems
Statistical Properties Control Problems
2015/8/5
The statistical properties of the certainty equivalence control rule and of the least squares
estimates generated by this rule are examined experimentally in a linear model with two
unknown paramete...
On Azema-Yor processes, their optimal properties and the Bachelier-Drawdown equation
optimal properties Bachelier-Drawdown equation
2010/10/29
We study the class of Az´ema–Yor processes defined from a general semimartingale with a continuous running supremum process. We show that they arise as unique strong solutions of the Bachelier s...
Statistical Properties of Fluctuations: A Method to Check Market Behavior
Statistical Properties Fluctuations Check Market Behavior
2010/11/1
We analyze the Bombay stock exchange (BSE) price index over the period of last 12 years. Keeping in mind the large fluctuations in last few years, we carefully find out the transient, non-statistical ...
Finite-sample Properties of Maximum Likelihood and Whittle Estimators in EGARCH and FIEGARCH Models
EGARCH fractionally integrated EGARCH maximum likelihood estimator
2010/9/7
EGARCH models for conditionally heteroscedastic time series have attracted a steadily increasing degree of attention in financial econometrics and related fields. These models are able to represent so...
The Statistical Properties of Exponential ACD Models
Exponential ACD models generalized F distribution unconditional moments
2010/9/7
This paper examines some of the statistical properties of exponential ACD models. To allow for nonmonotonic hazard functions we use either the generalized Gamma or the generalized F distributions. Con...
The empirical properties of large covariance matrices
Covariance matrix spectrum spectral density
2010/10/29
The salient properties of large empirical covariance and correlation matrices are studied for
three datasets of size 54, 55 and 330. The covariance is defined as a simple cross product of the returns...
