Statistical Analysis of High Dimensional & Complex Data
The last years have seen the advent and development of many devices able to record and store an always increasing amount of complex and high dimensional data: 3D images generated by medical scanners, satellite remote sensing, system control datasets, administrative databases, mobile phone data, etc. The analysis of these complex and high dimensional data poses new challenging problems and requires the development of novel statistical models and computational methods, fueling many fascinating and fast-growing research areas of modern statistics. It provides also an invaluable insight for the control and optimization of key processes of business and industrial sectors, of life-sciences, and of healthcare management.
The Applied Statistics group at MOX, in collaboration with domain experts from the private and public sector, is involved in the study of: functional data, compositional data, tensor data, neuroimaging and image data, network data, spatial and space-time data, epidemiological, healthcare, administrative, pharmaceutical data, and vital signals.
