1. ML (Maximum Likelihood) Estimation Key idea: infer the parameter θ∗ from sampled data that maximizes the likelihood (2)θ∗=argmaxθp(X|θ) Flip-coin example. argmaxΠθm(1−θ)n generalized prob., with θ as parameter argmaxΠf(θ)m(1−f(θ))n Likeli...
Statistical Bayesian channel estimation is effective in suppressing noise floor for high SNR, but its performance degrades due to less reliable noise estimation in low SNR region. Based on a robust nonlinear de-noising technique for small signal, a simplified joint maximum likelihood and Bayesian ...

When using ML estimation, most often s = p + k, the total number of parameters in the model. The proper formulas and application of these formulas under REML is still debated; see Gurka (2006) for a summary of the various viewpoints and forms specific to REML model selection. The ...
Parameter estimation via maximum likelihood and Bayesian inference in the AR(1) are also discussed. WEEK 2 Week 2: The AR(p) process This module extends the concepts learned in Week 1 about the AR(1) process to the general case of the AR(p). Maximum likelihood estimation and Bayesian ...

1. 极大似然估计(Maximum likelihood estimation) 假设有一堆独立同分布数据X1,…,XnX1,…,Xn,其PDF为p(x;θ)p(x;θ),其中θθ为模型参数,则其似然函数为: Ln(θ)=∏i=1np(Xi;θ)Ln(θ)=∏i=1np(Xi;θ) 而极大似然估计就是要找到参数θθ,使得似然函数的值最大。这意思就是找到一个参数θθ...
Here, we apply the maximum likelihood method for estimation of the transition probabilities. In the maximum likelihood method, the transition probabilities are found such that the probability of getting the observed dataset is maximized. To avoid numerical underflow, the logarithm of the product of ...
