Mean residual life function
Computes the mean residual life function of the extended Chen-Poisson (ecp) distribution.
ecp_mrl(x, lambda, gamma, phi)
x
: vector of quantiles.lambda, gamma
: parameter values > 0.phi
: parameter value != 0.Estimated value of mean residual life function, based on numerical integration.
ecp_mrl(x = 5, lambda = .1, gamma = .5, phi = - .2)
