calibrate_step_nls: calibrate_step_nls

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

Description

Stepwise estimation of true resistivities and thicknesses of a VES.

Usage

calibrate_step_nls(ves, iterations = 30, ireport = 10, max.layers = 10,
  trace = TRUE)

Arguments

ves	A VES object
iterations	An integer specifying the maximum number of iterations
ireport	An integer specifying the report interval
max.layers	An integer specifying the maximum number of layers to include in the sequential estimation.
trace	A logical flag to indicate if the optimization information must be traced

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 (ResiduSpatial Data Analysis in Ecology and Agricultureal 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
