CI-FAS_GMM_step

CI-FAS_GMM_step: Fourier Amplitude Spectra (FAS)-based model coefficients (stepwise regression). It contains the coefficients and uncertainty terms of the non-ergodic FAS ground motion model calibrated on the CI dataset by Sgobba et al (2022) using a mixed-effect stepwise regression technique.
The parametric table CI-FAS_GMM_step is distributed as a .zip file, containing:

• a parametric table in CSV format (semicolon separeted), containing the list of the model coefficients at each frequency and the related uncertainty terms;
• a dictionary (.txt files) explaining the abbreviations fields of the parametric table.
