Efficient approximation of first passage time densities for diffusion processes based on the First Passage Time Location (FPTL) function.

The main goal of this package is drawing the membership function of the fuzzy p-value which is defined as a fuzzy set on the unit interval for three following problems: (1) testing crisp hypotheses based on fuzzy data, see Filzmoser and Viertl (2004) <doi:10.1007/s001840300269>, (2) testing fuzzy hypotheses based on crisp data, see Parchami et al. (2010) <doi:10.1007/s00362-008-0133-4>, and (3) testing fuzzy hypotheses based on fuzzy data, see Parchami et al. (2012) <doi:10.1007/s00362-010-0353-2>. In all cases, the fuzziness of data or / and the fuzziness of the boundary of null fuzzy hypothesis transported via the p-value function and causes to produce the fuzzy p-value. If the p-value is fuzzy, it is more appropriate to consider a fuzzy significance level for the problem. Therefore, the comparison of the fuzzy p-value and the fuzzy significance level is evaluated by a fuzzy ranking method in this package.

A collection of functions for calculating Floristic Quality
    Assessment (FQA) metrics using regional FQA databases that have been
    approved or approved with reservations as ecological planning models
    by the U.S. Army Corps of Engineers (USACE). For information on FQA
    see Spyreas (2019) <doi:10.1002/ecs2.2825>. These databases are stored
    in a sister R package, 'fqadata'. Both packages were developed for the
    USACE by the U.S. Army Engineer Research and Development Center’s
    Environmental Laboratory.

Contains regional Floristic Quality Assessment databases that
    have been approved or approved with reservations by the U.S. Army
    Corps of Engineers (USACE). Paired with the 'fqacalc' R package, these
    data sets allow for Floristic Quality Assessment metrics to be
    calculated. For information on FQA see Spyreas (2019)
    <doi:10.1002/ecs2.2825>. Both packages were developed for the USACE by
