似然估计（Likelihood Estimation）是统计学中用于估计模型参数的核心方法。其核心思想是：在给定观测数据的前提下，通过寻找最可能生成这些数据的参数值，实现对模型参数的优化估计。以下从定义、原理和应用三方面展开说明：
定义与数学表达
似然估计通过构建似然函数（Likelihood Function）衡量参数取值的合理性。假设观测数据集为(X = {x_1, x2, ..., xn})，模型参数为(theta)，则似然函数定义为： $$ L(theta | X) = prod{i=1}^n P(xi | theta) $$ 最大似然估计（MLE）即求解使(L(theta | X))最大化的(hat{theta})，公式为： $$ hat{theta}{text{MLE}} = argmax{theta} L(theta | X) $$
