WebJun 9, 2024 · In this case we will implement Golden Section Search method to find extremum value in a sine graph as shown in figure 1 and 2. For that we need to create a sine function as below. def func_fx(x): fx=np.sin (x) return fx. To select a correct optimum value, we need to know the position of interior points one to another. WebThe F ratio is drawn from a distribution. If we assume the null hypothesis is true we get one distribution, and if we assume that it is false with various assumptions about effect size, sample size, and so forth we get another distribution. We then do a study and get an F value. When the null hypothesis is false, it is still possible to get an ...
