Loss
Adds the first order and 2nd order loss functions to the DistributionFunctionIfc.
Inheritors
Functions
Returns the F(x) = Pr{X <= x} where F represents the cumulative distribution function
Returns an array of probabilities each representing F(x_i). The CDF is evaluated for each point in the input array x and the probabilities are returned in the returned array.
Returns the probability of being in the interval, F(upper limit) - F(lower limit) Be careful, this is Pr{lower limit < = X < = upper limit} which includes the lower limit and has implications if the distribution is discrete
Returns the Pr{x1 <= X <= x2} for the distribution. Be careful, this is Pr{x1 <= X <= x2} which includes the lower limit and has implications if the distribution is discrete
Computes the complementary cumulative probability distribution function for given value of x. This is P{X > x}
Computes the first order loss function for the function for given value of x, G1(x) = Emax(X-x,0)
Provides the inverse cumulative distribution function for the distribution
Computes x_p where P(X <= x_p) = p for the supplied array of probabilities. Requires that the values within the supplied array are in (0,1)
Computes the 2nd order loss function for the distribution function for given value of x, G2(x) = (1/2)Emax(X-x,0)*max(X-x-1,0)
Returns the standard deviation for the distribution as the square root of the variance if it exists
