| quape3 {lmomco} | R Documentation |
This function computes the quantiles of the Pearson Type III distribution given
parameters (xi, α, and gamma) of the distribution computed by
parpe3. The
quantile function of the distribution has no explicit form (see
cdfpe3). The parameters have the following interpretations: xi is a location parameter, α is a scale parameter, and
gamma is a shape parameter.
quape3(f, para)
f |
Nonexceedance probability (0 <= F <= 1). |
para |
The parameters from parpe3 or similar. |
Quantile value for nonexceedance probability F.
