![عکس صفحه اول مقاله: On the Lp-metric between a probability distribution and its distortion On the Lp-metric between a probability distribution and its distortion](/preview/png/5076911.png)
In actuarial theory, the Lp-metric is used to evaluate how well a probability distribution approximates another one. In the context of the distorted expectation hypothesis, the actuary replaces the original probability distribution by a distorted probability, so it makes sense to interpret the Lp-metric between them as a characteristic of the underlying random variable. We show in this paper that this is a characteristic of the variability of the random variable, study its properties and give some applications.
⺠We interpreted the Lp-metric between a probability distribution and its distortion as a measure of dispersion. ⺠We show that the measure satisfies the axioms of Bickel and Lehmann (1976). ⺠In particular, this measure is consistent with the dispersive order. ⺠We suggest a family of premium principles based on the new family of measures of dispersion.
