Accurate portfolio risk-return structure modelling by Hossain, Nafees

“…Markowitz's modem portfolio theory has played a vital role in investment portfolio management, which is constantly pushing the development on volatility models. Particularly, the stochastic volatility model which reveals the dynamics of conditional volatility. …”

Exploring the Lived-Experience of business model innovation by Sangham, Mehul Anilrai

“…Due to increasingly complex and uncertain environments, businesses must deal with multiple competing and often opposing models, what we may call 'ontological relativity'. …”

Modelling of batch and fed-batch ethanol fermentation by Glyn, Julian E H

“…Growth rates were calculated and the data used to test the applicability of eight empirical kinetic models. The form proposed by Levenspiel, combining the concept of a limiting ethanol concentration with a power-law form, gave the best results with these data. …”

The use of correspondence analysis in building loglinear models by Parry, Charles David Heber

“…Correspondence Analysis (an exploratory data analysis procedure) and Log-linear Model building (a confirmatory data analysis procedure) are discussed before an investigation is undertaken to ascertain whether they can be used in conjunction. …”

On improving the forecast accuracy of the hidden Markov model by Rooney, Thomas J A

“…The forecast accuracy of a hidden Markov model (HMM) may be low due first, to the measure of forecast accuracy being ignored in the parameterestimation method and, second, to overfitting caused by the large number of parameters that must be estimated. …”

Gleason solutions and canonical models for row contractions by Ramanantoanina, Andriamanankasina

“…This thesis extends the deBranges-Rovnyak model for completely non-coisometric (CNC) contractions to the setting of row contractions from several copies of a Hilbert space into itself. …”

Bayesian model selection with applications to radio astronomy by Mootoovaloo, Arrykrishna

“…In the first part, the idea is to create a supermodel by combining two models using a hyperparameter, which we call α. Setting α = 0 or 1 switches each of the models off. …”

Implementation of Bivariate Unspanned Stochastic Volatility Models by Cullinan, Cian

“…Unspanned stochastic volatility term structure models have gained popularity in the literature. This dissertation focuses on the challenges of implementing the simplest case – bivariate unspanned stochastic volatility models, where there is one state variable controlling the term structure, and one scaling the volatility. …”

Pricing with Bivariate Unspanned Stochastic Volatility Models by Wort, Joshua

“…Unspanned stochastic volatility (USV) models have gained popularity in the literature. USV models contain at least one source of volatility-related risk that cannot be hedged with bonds, referred to as the unspanned volatility factor(s). …”

Articulated Statistical Shape Modelling of the Shoulder Joint by Alemneh, Tewodros

“…The aim of this project was to develop an analysis framework for shoulder joint kinematics via the use of articulated statistical shape models (ASSMs). Articulated statistical shape models extend conventional statistical shape models by combining the shape variability of anatomical objects collected from different subjects (statistical shape models), with the physical variation of pose between the same objects (articulation). …”
