Time series modeling

Time series analysis is an essential field in data analysis, particularly within forecasting and prediction domains. Researching and building time series models play a crucial role in understanding and predicting the temporal dynamics of various phenomena. In mathematics, time series data is defined as data points indexed in chronological order and have a consistent time interval between consecutive observations.

Modern civilization is heavily dependent on energy, which burdens the energy sector. Therefore, a highly accurate energy consumption forecast is essential to provide valuable information for efficient energy distribution and storage. This study proposed a hybrid deep learning model, called I-CNN-JS, by incorporating a jellyfish search (JS) algorithm into an ImageNetwinning convolutional neural network (I-CNN) to predict weekahead energy consumption.

The rationale for this study is that the social enterprise sector provides an important locale in which to situate research that aims to identify the impact of ICTs on development. Recognising the complex dynamics and range of actors involved in this diverse and emerging area of development practice, this study chooses to focus on the social enterprise sector. It is specifically concerned with mapping the external influences, use and impact of ICT on social enterprises in Cambodia.

Finance is considered as the lifeblood of the economy and it is integral to a country's economic growth and stability. However, this perception has been called into question, particularly following the global financial crisis, giving rise to new research questions. For example, does too much finance harm economic growth? And does the financial sector serve society's economic and social needs? This thesis aims to provide cross-sectional and time-series evidence on the macroeconomic consequences of financialisation in an international context.

This dissertation is composed of two parts, an integrative essay and a set of published papers. The essay and the collection of papers are placed in the context of development and application of time series econometric models in a temporal-axis from 1970s through 2005, with particular focus in the Marketing discipline. The main aim of the integrative essay is on modelling the effects of marketing actions on performance variables, such as sales and market share in competitive markets.

The central objective of the thesis "An economic analysis of the Australian Baby Bonus" is to examine the nature of the fertility response of Australian families to the financial incentive of the Baby Bonus. The efficacy of the policy in determining a change in both fertility and the timing of births is assessed by exploring the time series properties of national and Victorian fertility measures, while controlling for other possible determinants of fertility choice.

Thesis with the aim of focusing on two main issues. The first is time series modeling by states in which each state is a deterministic probability distribution (normal distribution). Based on the experimental results to assess the suitability of the model. Second, combine Markov chains and fuzzy time series into new models to improve forecast accuracy. Expand the model with high-level Markov chains to be compatible with seasonal data.

This thesis examines empirically whether there is a link between education and economic growth in Chile during the period 1973-2005. This is done through the adoption of time-series analysis and co-integration techniques. Based on economic theory and empirical findings, potential implications for Chilean educational policy are then discussed.
