Conversion of Conditional Nonexceedance Probability to Annual Nonexceedance Probability
Description
This function converts the conditional cumulative distribution function of to a cumulative distribution function
based on the probability level of the left-hand threshold. It is recommended that this threshold (as expressed as a probability) be that value returned from
x2xlo
in attribute pp
. The conversion is simple
where the term corresponds to the estimated probability or plotting position of the left-hand threshold.
This function is particularly useful for applications in which zero values in the data set require truncation so that logarithms of the data may be used. But also this function contributes to the isolation of the right-hand tail of the distribution for analysis by conditionally trimming out the left-hand tail at the analyst's discretion.
