x, q |
vector of quantiles. |
mu, sigma, a |
location, scale and shape parameters. Scale and shape must be positive. |
log, log.p |
logical; if TRUE, probabilities p are given as log(p). |
lower.tail |
logical; if TRUE (default), probabilities are P[X ≤ x] otherwise, P[X > x]. |
n |
number of observations. If |
If Z ~ Normal(0, 1) and U ~ Uniform(0, 1), then Z+U follows Bhattacharjee distribution.
Probability density function
f(z) = 1/(2*a) * (Φ((x-μ+a)/σ) - Φ((x-μ+a)/σ))
Cumulative distribution function
F(z) = σ/(2*a) * ((x-μ)*Φ((x-μ+a)/σ) - (x-μ)*Φ((x-μ-a)/σ) + φ((x-μ+a)/σ) - φ((x-μ-a)/σ))
