pBeta.4P | R Documentation |
Function for calculating the proportion of observations up to a specifiable quantile under the Four-Parameter Beta Distribution.
pBeta.4P(q, l, u, alpha, beta, lower.tail = TRUE)
q |
The quantile or a vector of quantiles for which the proportion is to be calculated. |
l |
The first (lower) location parameter. |
u |
The second (upper) location parameter. |
alpha |
The first shape parameter. |
beta |
The second shape parameter. |
lower.tail |
Whether the proportion to be calculated is to be under the lower or upper tail. Default is |
A vector of proportions of observations falling under specified quantiles under the four-parameter Beta distribution.
# Assume some variable follows a four-parameter Beta distribution with
# location parameters l = 0.25 and u = 0.75, and shape parameters alpha = 5
# and beta = 3. To compute the cumulative probability at a specific point of
# the distribution (e.g., 0.5)
# using pBeta.4P():
pBeta.4P(q = 0.5, l = 0.25, u = 0.75, alpha = 5, beta = 3)
