Geostatistics and Data Processing
Objectives
Theory and applications of methods of analysis and data processing used in geosciences (land and space) and more broadly in engineering, such as:
- Sampling and estimation problems (of an average, a distribution)
- Regression methods (single, multiple)
- Problems of interpolation and extrapolation of data in space and time
Description
A. STATISTICAL BASIS:
- Distribution Function, Proba Density, Moments and Other Statistics
- Constructing an empirical F.d.R by points or histograms
- Estimation or adjustment of a model law (e.g., by the method of moments)
- Sampling: sampling uncertainty; Jack-Knife method
- Multivariate proba laws (attached, marginal, conditional: Bayes th)
- Variance-covariance matrix and correlation matrix
- Simple regression Y = aX + b (reinterpretation in terms of optimal estimation)
B. APPRENTICES - (depending on years and case studies):
- Multiple regression Y = A1.X1 + ... + Ak.Xk + b
- Bayesian estimation of state vectors / application to time signals
- Binary variables, random processes of failures, rare events Delaunay Triangulation & Voronoi Polygons
- Bayesian estimation of state vectors / application in space (x, y, z): geostatistics, kriging, co-kriging
TYPES OF METHODS
"Non-statistical" methods of data analysis
- Spatial interpolation and spatial averaging by non-statistical method
- Wavelet analyzes
TYPES OF DATA
- In time (geophysical signal processing, hydroreweather, hydrological);
- In space (methods of interpolation and geostatistical estimation).
Examples:
- Time data or "signals" (time series sampled in time
- Failures, exceeding thresholds: reliability analyzes and risk studies
- Spatial data - sampled in space (x, y, z)
TYPES OF APPLICATIONS:
The case studies are drawn from earth sciences and hydrology as well as from the junction between industrial and environmental applications (construction failures, civil engineering, mining engineering, risk studies / nuclear waste management, etc.).
