F test for a CFAR process to specify the CFAR order.
F_test_cfar(f, p.max = 6, df_b = 10, grid = 1000)
The function outputs F test statistics and their p-values.
the functional time series.
the maximum CFAR order. Default is 6.
the degrees of freedom for natural cubic splines. Default is 10.
the number of gird points used to construct the functional time series and noise process. Default is 1000.
