stationary,转换的,就像火车站一样,处于中途的状态,或者一切处于停滞的状态,也就是说在这个特殊的点,函数变化率为 0。 很明显,为找到 stationary point 是最大值,还是最小值,我们需要判断,函数是从递增,一直到 0,再递减的吗? 如果是,二次导数,代表了一次导数的变化率,则为一个小于零的值。 好,stationary po...
摘要: The likelihood function for the stochastic frontier model is shown to possess an unusual stationary point which may or may not be a maximum. A condition is given to determine if the point is a maximum, and the result is interpreted in the context of specification and estimation....
Q1 Logarithmic exponential functions利用等式两边同取对数的方法,解指数方程,较为常规; Q2 Differentiation微分乘法法则求解 stationary point,需要解三角函数方程,难度适中; Q3 Complex number确定square roots的问题,常规方法; Q4 Logarithmic ...
Convergence analyses of evolutionary pattern search algorithms (EPSAs) have shown that these methods have a weak stationary point convergence theory for a broad class of unconstrained and linearly constrained problems. We describe how th... WE Hart - Proceedings of the genetic and evolutionary computa...
We obtain the rigorous uniform asymptotics of a particular integral where a stationary point is close to an endpoint. There exists a general method introduced by Bleistein for obtaining uniform asymptotics in this situation. However, this method does not provide rigorous estimates for the error. Inde...
Differentiation贯穿了整个A-Level数学,其中AS阶段经常涉及到的就是求stationary point以及判断stationary point的nature,也就是判断这个稳定点是最大值还是最小值的问题。 下面我们通过具体的例子来总结一下,AS阶段differentiation的常见考点: 有关的就是increasin...
