calibrate_ilsqp: calibrate_ilsqp

In khaors/rves: R package for the interpretation of Vertical Electric Soundings

Description

Function to estimate the layer parameters (real resistivities and thicknesses) from a VES measurements using the ILPSQ (Iterative Least-Squares Procedure) with Singular Value Decomposition proposed by Muiuane and Pedersen (1999).

Usage

calibrate_ilsqp(ves, iterations = 30, ireport = 10)

Arguments

ves	A VES object
iterations	An integer specifying the maximum number of iterations
ireport	An integer specifying the report interval

Value

This function returns a list with the following entries:

• par: A numeric vector with the values of the layer resistivities and thicknesses

• value: The value or the RSS (Residual sum of squares)

• rel.error: The value of the relative error (in percentage)

• cal.error: A matrix with the RSS and relative error at each iteration
