  1. Fulltext. Application of inverse Gaussian distribution to occupational exposure data.

    Article - En anglais


    Occupational exposure concentrations are generally assumed to vary in a log-normal manner.

    However, because the mean of random samples from a log-normal distribution is not log-normally distributed, it cannot, in theory, deal with the changes in the distribution of time-weighted average (TWA) values when the averaging time varies.

    On the other hand, inverse Gaussian distribution, which is similar to a log-normal one, offers the advantage of reproducibility.

    This paper proposes the application of inverse Gaussian distribution to occupational exposure data.

    First, inverse Gaussian distribution was compared with the log-normal one.

    Second, in order to simplify the application, the percentiles of inverse Gaussian distribution with CV=0.25 to 4 were calculated.

    Finally, this distribution was applied to occupational exposure data.
