Evaluate logistically initially and gausian eventually

This function evaluates the calculated values from an indicator using a general logistic function

Usage

bln_evaluate_logistic_gaus_down(x, b, x0, v, optimum, optimum_ofset = 1.5)

Arguments

x

(numeric) The values of a calc function to be converted to an evaluation

b

(numeric) The growth rate

x0

(numeric) The offset of the x-axis

v

(numeric) Affects the growth rate near the maximum

optimum

(numeric) Point where x has approximaltly reached the optimal value

optimum_ofset

(numeric) Multiplication factor to determine at what point gaussian evaluation should be applied

Value

A transformed variable after applying a logistic evaluation function. A numeric value.
