随机向量的率函数何时是严格凸的?
When is the rate function of a random vector strictly convex?
摘要:
本文给出了$R^d$中随机向量的速率函数严格凸的一个充要条件。当随机向量具有有限的拉普拉斯变换时,这个条件总是满足的。在较弱的条件下,我们还完整地描述了速率函数的有效域。
英文摘要:
We give a necessary and sufficient condition for strict convexity of the rate function of a random vector in $R^d$. This condition is always satisfied when the random vector has finite Laplace transform. We also completely describe the effective domain of the rate function under a weaker condition.
