Fit Exponential Growth Model with a Heuristic Linear Method

Description

Helper functions for handling linear fits.

Usage

lm_window(x, y, i0, h = 5)

lm_parms(m)

Arguments

x	vector of independent variable (e.g. time).
y	vector of dependent variable (concentration of organisms).
i0	index of first value used for a window.
h	with of the window (number of data).
m	linear model (lm) object

Details

The functions are used by a heuristic linear approach, similar to the “growth rates made easy”-method of Hall et al. (2013).

Value

linear model object (lm_window resp. vector with parameters of the fit (lm_parms).
