Aspects of bivariate time seriesSeeletse, Solly Matshonisa 11 1900 (has links)
Exponential smoothing algorithms are very attractive for the practical world
such as in industry. When considering bivariate exponential smoothing
methods, in addition to the properties of univariate methods, additional
properties give insight to relationships between the two components of a
process, and also to the overall structure of the model.
It is important to study these properties, but even with the merits the
bivariate exponential smoothing algorithms have, exponential smoothing
algorithms are nonstatistical/nonstochastic and to study the properties within
exponential smoothing may be worthless.
As an alternative approach, the (bivariate) ARIMA and the structural models
which are classes of statistical models, are shown to generalize the exponential
smoothing algorithms. We study these properties within these classes as they
will have implications on exponential smoothing algorithms.
Forecast properties are studied using the state space model and the Kalman
filter. Comparison of ARIMA and structural model completes the study. / Mathematical Sciences / M. Sc. (Statistics)

Going beyond evidence based and common factors approaches: a social constructionist model of therapeutic factorsVan Zyl, Francois Nicolaas 02 1900 (has links)
Text in English / The inception of psychology as a practicing profession in 1938 brought with it a continuing scientific struggle geared towards cementing its place as a value-adding health service in the form of psychotherapy. Concepts such as Empirically Supported Treatments (ESTs), Evidence Based Treatments (EBTs) and Evidence Based Practice in Psychology (EBPP) arose out of research attempts to scientifically prove the efficacy of psychological treatment versus psychiatric medications or versus no treatment. This focus on evidence in psychotherapy partly stems from, but also influences public policy in the form of practice and training mandates as well as government and insurance funding policies for psychotherapy. At present ESTs, EBTs and EBPP are the source of polarisation among psychologists who argue for either sides of this controversy, raising questions on a practical/policy level as well as an epistemological level. This thesis differentiates between ESTs, EBTs and EBPP as well as the Common Factors approach and continues to critically investigate the advantages, practical/policy implications and epistemological critiques against these approaches. Some of the identified shortfalls resulting from unwarranted epistemological (empirical) assumptions are addressed by proposing a social constructionist model of therapeutic factors based on social constructionist- and eco-systemic theories. The proposed model allows therapists to employ EBT’s in conjunction with various other (excluded) approaches that are available in their arsenal of treatments. Clinical case studies are used to illustrate the model’s practical operation in therapeutic contexts. / Psychology / Ph.D. (Psychology)
