Calculates the parameters of the Johnson Quantile-Parameterised Distribution
Description
Calculates the parameters of the Johnson Quantile-Parameterised Distribution
Usage
jqpd(x, lower = 0, upper = Inf, alpha = 0.1)
Arguments
x |
a length 3 numeric vector containing the symmetric percentile triplet values used to parameterise the distribution. |
lower |
a real number specifying the lower bound of the distribution. (default: 0) |
upper |
a real number specifying the upper bound of the distribution. A value of Inf indicates a semi-bounded distribution. (default: Inf) |
alpha |
a real number (between 0 and 0.5) used to describe the symmetric percentile triplet for which the quantile values provided in 'x' correspond. For instance, alpha = 0.1 (default value) indicates the percentiles used are [0.1, 0.5, 0.9]. |
