Nonparametric Monitoring for Geotechnical Structures Subject to Long-Term Environmental Change

Procedures of conventional parametric approaches and proposed nonparametric approaches. Using output-only (or response-only) data in modeling, the proposed approach does not require defining explicit relationships between the system input, environmental effects, and the system output, which are required in conventional parametric approaches.
