WebApr 13, 2024 · Cyber incidents are among the most critical business risks for organisations and can lead to large financial losses. However, previous research on loss modelling is based on unassured data sources because the representativeness and completeness of op-risk databases cannot be assured. Moreover, there is a lack of modelling approaches that … WebA(z) is the integral of the standardized normal distribution from −∞to z(in other words, the area under the curve to the left of z). It gives the probability of a normal random variable not being more than zstandard deviations above its mean. Values of zof particular importance:
