Short-Term Inflation Forecasting Models For Nigeria, Sani I. Doguwa, Sarah O. Alade Dec 2013

Short-Term Inflation Forecasting Models For Nigeria, Sani I. Doguwa, Sarah O. Alade

CBN Journal of Applied Statistics (JAS)

Short-term inflation forecasting is an essential component of the monetary policy projections at the Central Bank of Nigeria. This paper proposes four short-term headline inflation forecasting models using the SARIMA and SARIMAX processes and compares their performance using the pseudo-out-of-sample forecasting procedure over July 2011 to September 2013. According to the results the best forecasting performance is demonstrated by the model based on the all items CPI estimated using the SARIMAX model. This model is, therefore, recommended for use in short-term forecasting of headline inflation in Nigeria. The forecasting performance up to eight months ahead, of the models based on …

An Efficient Two Sample Capture-Recapture Model With High Recaptures, Danjuma Jibasen, Yusuf J. Adams Dec 2013

An Efficient Two Sample Capture-Recapture Model With High Recaptures, Danjuma Jibasen, Yusuf J. Adams

CBN Journal of Applied Statistics (JAS)

This paper proposed an efficient two sample capture-recapture model (Ma) with high recaptures and compared it with the existing models like the model of no factor effect (Mo), behavioral response model (Mb) and the Petersen model (Ms), using simulated data. We found that the Petersen model provides a better estimate of the population size when the observations follow a hypergeometric distribution and the population is overestimated when recapture is high. It was also found that the proposed model provides a better estimator of the population size than the existing ones when the recapture is high. This model is particularly useful …

Causal Relationship Between Stock Market Index And Exchange Rate: Evidence From Nigeria, Abdulrasheed Zubair Dec 2013

Causal Relationship Between Stock Market Index And Exchange Rate: Evidence From Nigeria, Abdulrasheed Zubair

CBN Journal of Applied Statistics (JAS)

This paper uses Johansen’s cointegration to test for the possibility of cointegration and Granger-causality to estimate the causal relationship between stock market index and monetary indicators (exchange rate and M2) before and during the global financial crisis for Nigeria, using monthly data for the period 2001–2011. Results suggest absence of long-run relationship before and during the crisis. The Granger-causality tests show a uni-directional causality running from M2 to ASI before the crisis while during the period of the crisis there is absence of causality between the variables. This suggests that ASI show responsiveness to M2. Thus, absence of the direct …

Nigerian Stock Index: A Search For Optimal Garch Model Using High Frequency Data, Olaoluwa Simon Yaya Dec 2013

Nigerian Stock Index: A Search For Optimal Garch Model Using High Frequency Data, Olaoluwa Simon Yaya

CBN Journal of Applied Statistics (JAS)

This paper attempts to fit the best Generalized Autoregressive Conditional Heteroscedastic (GARCH) model for All Share Index (ASI) of Nigerian Stock Exchange (NSE) returns. A search is made on various GARCH variants specified on the assumptions of stationarity and asymmetry. Fractionally integrated types are also considered to capture the possibility of return series having property of long range dependency. The parameter estimations are carried out on the assumptions of normality and non-normality of GARCH innovations, with models and forecasts evaluated using information criteria and loss functions respectively. Under normality assumption, Hyperbolic GARCH (HYGARCH(1,d,1)) model is selected and Integrated GARCH (IGARCH(1,1)) …

Me And Goldilocks...Searching For What Is “Just Right” In Trauma Research: An Autoethnography, Rosemary C. Reilly Nov 2013

Me And Goldilocks...Searching For What Is “Just Right” In Trauma Research: An Autoethnography, Rosemary C. Reilly

The Qualitative Report

This is a reflexive account of the tensions and dilemmas emerging from my experience as a woman qualitative researcher researching trauma and tragedy in communities. Framed as an autoethnography, using my conflictual childhood feelings about Goldilocks as an overarching metaphor, I will weave fairy tale and experience into an examination of the impact I can have on individuals, families, and communities in the course in pursuing research. I will attempt to highlight the edges of research culture and ethical conduct, the politics of trespass and the rights of individuals and communities while trying to discover what is “just right.”

Brand Equity Planning With Structuralist Rhetorical Semiotics: A Conceptual Framework, George Rossolatos Nov 2013

Brand Equity Planning With Structuralist Rhetorical Semiotics: A Conceptual Framework, George Rossolatos

The Qualitative Report

This paper furnishes a structuralist rhetorical semiotic conceptual framework for brand equity planning. The main source of brand equity that is employed for exemplification purposes is the advertising filmic text. The conceptual framework assumes as its general blueprint Greimas’s generativist model of the trajectory of signification. Structuralist operations and operations of rhetorical transformation are posited as the basis for the generation of superior brand associations. The conceptual model put forward challenges the Greimasian assumption that a depth semantic structure is reducible to a binarist rationale, while adopting a connectionist approach in the form of associative networks. At the same time, …

Calibrating The Human Instrument: Understanding The Interviewing Experience Of Novice Qualitative Researchers, Margarita S. Peredaryenko, Steven Eric Krauss Oct 2013

Calibrating The Human Instrument: Understanding The Interviewing Experience Of Novice Qualitative Researchers, Margarita S. Peredaryenko, Steven Eric Krauss

The Qualitative Report

Scientific instruments often undergo calibration to ensure that they will produce results that meet or exceed defined criteria within a specified degree of confidence. Such calibration almost always refers to mechanical instruments, those used primarily in the physical sciences. Rarely is the notion of calibration used in relation to the social and human sciences, especially in the context of qualitative research where the human being is the main research instrument. The focus of this study was to explore the experiences of novice human instruments undergoing a process similar to that of calibration. In doing so, we studied how novice qualitative …

Alive In The Reading: Nayaran And Chekhov, Laurie Ecke Oct 2013

Alive In The Reading: Nayaran And Chekhov, Laurie Ecke

The Qualitative Report

Kirin Nayaran's Alive in the Writing: Crafting Ethnography in the Company of Chekhov is a five - section book about finding "company amid the often isolating and difficult aspects of writing" (p. xiii). As an English Literature major, I recall the basic tenets of story - writing: plot, setting, and characterization. Narayan's chapters offer a kinder entry. "Story and Theory" invoke Anton Chekhov as an ethnographic companion offering expertise about the essentials of writing a good story. "Place," "Person," and "Voice" take the innocent writer further in to the power of writing, until "Self" provides a denouement of sorts, when …

Prototype Modeling Vs. Item Response Theory – A Paradigm Shift For Measurement Professionals, Joseph Yeager, Linda Sommer, Juliette Faughnan, Christophe Geerkens Oct 2013

Prototype Modeling Vs. Item Response Theory – A Paradigm Shift For Measurement Professionals, Joseph Yeager, Linda Sommer, Juliette Faughnan, Christophe Geerkens

The Qualitative Report

In science, the usual research mode is to discover cause - and - effect mechanisms operating behind superficial reality. Aviation, for example, uses prototype modeling to develop improved aircraft from one generation to the next. In stark contrast to prototype modeling’s search for causal mechanisms, assessment technologies remain dominated by probability strategies — which is why psychological assessment lags behind the hard sciences. A major difference in results exists between inferences produced through item response theory versus the cause - effect prototyping strategies of aerospace and other techno - savvy industries. Parallel to aerospace strategies, systems analysis of language, using …
