Statistics in Industry: from Theory to Practice

Sala 6.4.30, FCUL, Lisboa

Por Ana Borges (Instituto Politécnico do Porto).

Abstract: Among the inherent objectives of Science, the simplification of reality, the explanation and resolution of problems are the most immediate. With the dynamic and scientific development of industrial processes, companies will increasingly benefit from the transfer of knowledge between the academy and the industrial poles, promoting a close articulation between theory and practice. In this sense, and particularizing for the area of Statistics, will be presented two studies developed within the scope of challenges proposed by companies in two different European Study Group with Industry (ESGI - https://ecmiindmath.org/study-groups/).

The first challenge, presented by EDP, focuses on the problem of forecasting electricity prices. We ajusted a model for the hourly prices of the Iberian Electricity Market (MIBEL) from January 1, 2015 to June 26, 2016. Resulting that a longitudinal approach, considering a mixed effects model, with day of the week as a fixed effect, group of hours as a random effect and an AutoRegressive component of order 7 describing the dependence within hours, returns a model that explains the intra-day and intra-hour dynamics of electricity prices per hour. The second challenge aimed to find a solution for the case study of performance evaluation of water meters, proposed by Infraquinta (Algarve, Portugal). The main objective was to discover the point of change in the water meter performance and the moment suited for its replacement. Making use of the Seasonal Trend Decomposition of followed by the detection of structural breaks in the trend component (directly related to the performance of the counter) it was possible to detect the breakpoints of the water meter.

Both of the presented challenges are intended to serve as clarifying examples of how the industry benefits directly from an approach to academia.

Overview: Currently, climate changes or alterations are known to be reflected on the stable isotope ratios of Hydrogen, Nitrogen, Carbon, Oxygen and Sulphur present in atmospheric gas forms, fresh or ocean water, as well as in plants and animals and organi

Objectives: Evolutionary theory provides a framework for understanding all living systems.

Objectives: To introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

Objectives: Natural history museums are privileged spaces for seminal research on different subjects of biological sciences such as biodiversity, evolution, ecology, biogeography and taxonomy.

Objectives: Provide students with basic workflows, platforms and tools to increase reproducibility at all scientific levels.

Objectives: Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

Objectives: The objective of this course is to introduce participants to the details of communication and writing scientific publications. The main emphasis is on the most common form, the “primary scientific paper”, but other forms will be covered.

Objectives: Lack of fertile land to feed the exponentially growing population, insufficient water availability and quality, changes in the flow of nutrients through the bio-geo-cycles (especially N and P) and climate and land use changes are impacting ecosystem

Objectives: Symbiosis is a key strategy for life on Earth.

Objectives: The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects. It aims at providing an integrated approach on urban socio-ecological systems.

Objectives: Citizen science can be part of the larger process of engaging people in new forms of interaction in scientific research, challenging scientists and citizens whilst enlarging scientific knowledge and providing learning opportunities for all part

Objectives: This course aims at: 1) exploring how scientists can use social media as tools to enhance the communication of their research and the dialogue with society, and 2) discussing the differences that exist in the work of scientists and journalists

Objectives: This course will teach how to apply the SWAT eco-hydrological model to assess the impacts of climate and associated changes on water-soil-plant interactions, and consequences to water resources, soil erosion and nutrient cycles.

Objectives: Provide students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.
