ApplyCombMod {pvcurveanalysis}

Apply a combined exponential and linear model

Description

a non linear model combining an exponential and a linear fit is applied to the data using the Gauss-Newton algorithm of nls. starting values are calculated based on the data. Weights are applied to the model based on the estimated insecurity of the data quality.

Usage

ApplyCombMod(data, y = "y", x = "x")

Arguments

data

data frame containg x and y data to which the model is ought to be applied to

y

name of column in data containing y data

x

name of column in data containing x data

Value
