WangEngels_prediction: DRC function: WangEngels_prediction

Description

DRC function: WangEngels_prediction

Usage

WangEngels_prediction(x, params)

Value

value with WangEngels response

Arguments

x

effective env_variable value

params

list of input parameter; xmin_value represents the minimal env_variable value above which growth response will happen ; xopt_value: optimal growth point, env_variable values here have the highest response; xmax_value represents the maximal env_variable value above which no growth response will happen according to the wang engel model.

Examples

WangEngels_prediction(10, params = list("xmin_value"=1,
                                       "xopt_value"=25,
                                       "xmax_value"=35,
                                        "r_value"=0.5))
