Discrete Chi-Square Method discovers solar forcing in El Niño time series: The Pacific Ocean as a bolometer measuring the solar dynamo light curve in real-time
离散卡方方法与厄尔尼诺时间序列中的太阳强迫:太平洋辐射计解释
Discrete Chi-square Method (DCM) can detect multiple signals superimposed on an arbitrary trend. DCM's backbone is Gauss-Markov theorem that Least Squares (LS) is the best unbiased estimator for linear regression models. DCM is robust because it computes numerous linear model LS fits. Discrete Fourier Transform and other frequency-domain methods have many application limitations. None of those limitations constrains DCM. Fisher-test provides signal significances and…
