Regular Variation of the Tail of a Subordinated Probability Distribution
Let F be a probability measure on the real line and G=Σ C(k)Fk*the probability measure subordinate to F with subordinator C restricted to the nonnegative integers. Let V(x) vary regularly of order ρ for x→ ∞ and either (1) V(x)F[x,∞)→ a≥ 0 or (2) $V(x)C[x,\infty)\rightarrow \gamma \geq 0.\ \text{If}...

Zusammenfassung: | Let F be a probability measure on the real line and G=Σ C(k)Fk*the probability measure subordinate to F with subordinator C restricted to the nonnegative integers. Let V(x) vary regularly of order ρ for x→ ∞ and either (1) V(x)F[x,∞)→ a≥ 0 or (2) $V(x)C[x,\infty)\rightarrow \gamma \geq 0.\ \text{If}\ \rho >1$ and F(-∞ ,0)=0, necessary and sufficient in order that V(x)G[x,∞)→ b, is that both (1) and (2) hold for suitable α and γ . For 0≤ ρ ≤ 1 the conditions are of different type. For two-sided F a different situation arises and only sufficient conditions are found. An application to renewal moments of negative order is given. |
