get_init_pars_logistic: get_init_pars_logistic

In miLAG: Calculates Microbial Lag Duration (on the Population Level) from Provided Growth Curve Data

get_init_pars_logistic

Description

Finds reasonable approximation for logistic growth curve parameters (K, lag. growth rate) based on the growth curve and some initial values These approximations will be used as the initial values for the proper optimization algorithm run later.

Usage

get_init_pars_logistic(
  data_this_curve,
  this_n0,
  init_K,
  init_lag,
  init_gr_rate,
  min_b = 0.2,
  min_a = 0.8
)

Arguments

data_this_curve	data from one specific growth curve with these two columns: time and biomass
this_n0	the initial biomass
init_K	initial value for the saturation parameter K
init_lag	initial value for the lag parameter
init_gr_rate	initial value for the growth rate
min_b	defaults to 0.2; mina and minb define where to look for exponential phase: it will be where the biomass is between min + (max-min)*(min_a TO min_b)
min_a	defaults to 0.8

Value

list of parameters: init_K, init_lag, init_gr_rate,
