Near Unit Root in the Spatial Autoregressive Model
Spatial autoregressive model Spatial unit root Near unit root Two stage least square Quasi-maximum likelihood estimatio
2016/1/19
This paper studies the spatial autoregressive (SAR) model for cross sectional data when the true spatial e¤ect parameter is near unity. We decompose the data generating process into an unstable compon...
Probit transformation for kernel density estimation on the unit interval
transformation kernel density estimator boundary bias local likelihood density estimation local log-polynomial density estimation
2013/4/27
Kernel estimation of a probability density function supported on the unit interval has proved difficult, because of the well known boundary bias issues a conventional kernel density estimator would ne...
Unified theoretical framework for unit root and fractional unit root
First autoregression fractional integration explosive processes unit root fractional unit
2012/11/22
To distinguish between purely fractionally integrated (FI) processes, we propose in this article an appropriate fractional Dickey-Fuller test (F-DF). This extends the familiar Dickey-Fuller (1979) typ...
Parameter estimation in a spatial unit root autoregressive model

2011/3/23
Spatial autoregressive model $X_{k,\ell}=\alpha X_{k-1,\ell}+\beta X_{k,\ell-1}+\gamma X_{k-1,\ell-1}+\epsilon_{k,\ell}$ is investigated in the unit root case, that is when the parameters are on the b...

Monitoring Procedures to Detect Unit Roots and Stationarity
Autoregressive unit root change-point control chart nonparametric smooth-ing sequential analysis weighted partial sum process

When analysing time series an important issue is to decide whether the time
series is stationary or a random walk. Relaxing these notions, we consider the problem to
decide in favor of the I(0)- or ...
Predictors of job satisfaction among doctors, nurses and auxiliaries in Norwegian hospitals: relevance for micro unit culture
job satisfaction Norwegian hospitals micro unit culture
2009/9/28
The professional values of medicine, the organizational and holistic skills of nurses and the practical experience of auxiliaries should all be valued in the building of interdependent micro teams.
Does Technological Learning Pay Off? Implications of Capability Accumulation for Techno-economic Performance Improvement in a Steelmaking Unit in Brazil (1997-2001)
technological capability accumulation learning processes latecomer firms
2009/9/25
This paper focuses on the implications of learning processes for technological capability accumulation and performance improvement. These relations are evaluated through a single case study in the ste...
Inference for MA(1) processes with a root on or near the unit circle
Inference for MA(1) processes a root on or near the unit circle
2009/9/22
This paper considers maximum likelihood estimation
(MLE) for MA(1) processes when the moving average parameter is on
or near the unit circle. The asymptotic theory to be presented allows
the use of...
Sojourn time of some reflected Brownian motion in the unit disk

2009/9/22
We study the heat diffusion in a domain with an obstacle
inside. More precisely, we are interested in the quantity of heat
in so far as a function of the position of the heat source at time 0. This

Let D, be the diameter of a partition of the interval [0, t]
by renewal moments of a standard Poisson process. Then DJln t + 1 for
t + co, in probability. Other theorems on diameters are obtained. J...

2009/3/20
Jiang, Dickey, and Kuo [12] gave the multivariate c-characteristic function and showed that it has properties similar to those of the multivariate Fourier transformation. We first give the multivariat...
