mathematical_model_evalR Documentation

Evaluation of the mathmatical model at given observed inputs and calibration parameters.

Description

This function evaluates the mathematical model at given observed inputs and calibration parameters.

Usage

mathematical_model_eval(input,theta,simul_type, emulator,
emulator_type,loc_index_emulator,math_model)

Arguments

input

a matrix of the observed inputs.

theta

a vector of calibration parameters.

simul_type

tpye of math model. If the simul_type is 0, it means we use the RobustGaSP R package to emulate the math model. If the simul_type is 1, it means the function of the math model is given by the user. When simul_type is 2 or 3, the mathematical model is the geophyiscal model for Kilauea Volcano. If the simul_type is 2, it means it is for the ascending mode InSAR data; if the simul_type is 3, it means it is for the descending mode InSAR data.

emulator

an S4 class of rgasp model from the RobustGaSP R Package.

emulator_type

a character to specify the type of emulator. 'rgasp' is for computer models with scalar-valued output and 'ppgasp' for computer models with vectorized output.

loc_index_emulator

a vector of the location index from the ppgasp emulator to output. Only useful for vectorized output computer model emulated by the ppgasp emulator.

math_model

a function for the math model to be calibrated.

Value

a vector of outputs from the math model or its emulator at given observed inputs and calibration parameters.
