Alternative estimation methods for survival models
… model and the Weibull model. The existing methods for estimating these parameters by the method of least-squares include using a log-transformation on the force of mortality data. We will propose another method of estimating these parameters that uses linear regression, and finding the …

On Terrorist Attacks and Estimation Methods
… a theoretical model of terrorist attacks and anestimation strategy which I compare to existing methods in the literature. The modeling approach was designed with terrorism in mind, but can be applied to other discrete dynamic decision processes with a latent component and a random payoff …

A comparison of slope estimation methods
The study evaluates widely used slope estimation algorithms with the aim of determining similarities or differences between results obtained by each, the accuracy of methods in modelling actual slope, and the suitability of these methods for site-specific and non-site specific applications. The …

Essays On Spatial Econometrics: Estimation Methods And Applications
… dissertation consists of four essays on the estimation methods and applications of spatial econometrics models. In the first essay, we consider a spatial econometric model containing spatial lags in the dependent variable and the disturbance terms with an unknown form of heteroskedasticity in …

Signal parameter estimation methods: The non-eigenvector based approach
An idea behind this dissertation is the estimation of signal parameters of a radio channel snapshot. The focal point here to utilize the high resolution estimation capabilities of subspace based methods in association with non-eigenvector based parameter estimation methods to reduce the complexity …

Conditional source-term estimation methods for turbulent reacting flows
Conditional Source-term Estimation (CSE) methods are used to obtain chemical closure in turbulent combustion simulation. A Laminar Flamelet Decomposition (LFD) and then a Trajectory Generated Low-Dimensional Manifold (TGLDM) method are combined with CSE in Reynolds-Averaged Navier Stokes (RANS) …

Precipitation Estimation Methods in Continuous, Distributed Urban Hydrologic Modeling
Quantitative precipitation estimation (QPE) remains a key area of uncertainty in hydrological modeling, particularly in small, urban watersheds which respond rapidly to precipitation and can experience significant spatial variability in rainfall fields. Few studies have compared QPE methods in …

Jump Variation in High-Frequency Asset Returns: New Estimation Methods
… variation and integrated variance based on the estimation scheme, suggesting careful attention must be paid to the method of decomposing conditional daily return variance into jump variation and integrated variance.
