ecld.quartic_Qp | R Documentation |
Compute the ATM location and ATM skew of Q_p in quartic model.
ecld.quartic_Qp(object, ki) ecld.quartic_Q(object, ki, otype) ecld.quartic_Qp_atm_ki(object, lower = -50, upper = -1.37) ecld.quartic_Qp_rho(object, atm_ki = NaN, lower = -50, upper = -1.37) ecld.quartic_Qp_skew(object, ki, dki = 0.1) ecld.quartic_Qp_atm_skew(object, dki = 0.1, lower = -50, upper = -1.37)
object |
an object of ecd class |
ki |
numeric, order of the moment to be computed |
otype |
character, specifying option type with either c or p. |
lower |
numeric, optional value to specify the lower bound of ATM root finding. This is often needed when the smile is collapsed in the left wing. |
upper |
numeric, optional value to specify the upper bound of ATM root finding This is often needed when the smile is collapsed significantly in the right wing. |
atm_ki |
numeric, if provided, take it as is without calculating again |
dki |
numeric, delta of ki for calculating slope |
numeric
