Regularity conditions是什么
Web中心极限定理(英语:central limit theorem,簡作 CLT)是概率论中的一组定理。 中心极限定理说明,在适当的条件下,大量相互独立随机变量的均值经适当标准化后依分布收敛于标准正态分布。 这组定理是数理统计学和误差分析的理论基础,指出了大量随机变量之和近 … WebJul 26, 2024 · In general, more regularity means more desirable properties. Typically this means one or several of the following: Higher integrability, i.e. a function lies in a more restrictive L p space, i.e. higher powers of the function are integrable. Higher differentiability, i.e. higher (weak) derivatives of the function exist.

The degrees of freedom of the limiting distribution is the difference between the number of free parameters specified by θ ∈Θ 0 and the number of free parameters specified by θ ∈Θ.
WebThen, later it says the following: "If a convex optimization problem with differentiable objective and constraint functions satisfies Slater's condition, then the KKT conditions provide necessary and sufficient conditions for optimality: Slater's condition implies that the optimal duality gap is zero and the dual optimum is attained, so x is ... WebThe regularity conditions include the following: the true parameter value θ must be interior to the parameter space, the log-likelihood function must be thrice differentiable, and the third derivatives must be bounded.
