Truncated loss

In statistics, a truncated distribution is a conditional distribution that results from restricting the domain of some other probability distribution. Truncated distributions arise in practical statistics in cases where the ability to record, or even to know about, occurrences is limited to values which lie above or below a given … See more The following discussion is in terms of a random variable having a continuous distribution although the same ideas apply to discrete distributions. Similarly, the discussion assumes that truncation is to a semi-open interval y … See more Suppose we wish to find the expected value of a random variable distributed according to the density $${\displaystyle f(x)}$$ and … See more Suppose we have the following set up: a truncation value, $${\displaystyle t}$$, is selected at random from a density, $${\displaystyle g(t)}$$, but this value is not observed.

Composite Goodness-of-Fit Tests for Left-Truncated Loss Samples

Usually the values that insurance adjusters receive are either left-truncated, right-censored, or both. For example, if policyholders are subject to a policy limit u, then any loss amounts that are actually above u are reported to the insurance company as being exactly u because u is the amount the insurance company pays. The insurer knows that the actual loss is greater than u but they don't know what it is. On the other hand, left truncation occurs when policyholders are subje… WebJul 1, 2024 · This paper presents a robust matrix completion model, which is suitable for a low sampling rate.
