Hi , R is a new language for me so sorry in advance if this error is to basic for posting. I have tried the R manual and search online for quite a few, if anyone could help i would be very thankful. Here is my code. kappa = 1.1 theta = 0.1 sigma = 0.4 rho = -0.6 v0 = 0.2 r = 0.05 T = 0.5 s0 = 1 K = 0.5 type = 1 Hestoncall = function(kappa,theta,sigma,rho,v0,r,T,s0,K,type) { u = 0.5 b

I am trying to obtain the grafic of a pdf . but this error keeps showing . Here is the code MXN.fd = function(x,alpha,beta,mu,delta) { A = (2*cos(beta/2))^(2*delta) B = 2*alpha*pi*gamma(2*delta) C = (beta*(x-mu))/alpha D = abs(gamma(delta + (complex(0,0,1)*(x-mu))/alpha)^2) M = A/B*exp(C)*D M plot(x,M,type="l",lwd=2,col="red") } alpha = 0.02612297 beta = -0.50801886 mu =

Hi, I am writing a function to plot a pdf of a distribution, GNL.pdf.fn = function(x,mu,sigma,alpha,beta,rho) { y = x-rho*mu cf.fn = function(s){ cplex = complex(1,0,1) temp1 = alpha*beta*exp(-sigma*s^2/2) temp2 = (alpha-cplex*s)*(beta+cplex*s) out = (temp1/temp2)^rho out } temp.fn = function(s){ (Mod(cf.fn(s)))*cos(Arg(cf.fn(s))-s*y) } int.fn =
