Risk Neutral Density Estimation

Instructions:

• These procedures can be downloaded individually, or together as one zip file: pdfest.zip . Place all files (including declaration files ending in ".dec" into your "/gauss/src" directory.

Individual Programs:

• jackrub.g Penalized smoothness method as described in Jackworth & Rubinstein (Journal of Finance,1997) (with Clamping)
• mlnorm.g & mlnorm.dec Estimate a mixture of log-noramls r.n. dist'n
• mvopt2.g & mvopt2.dec Calculate mean and variance of returns to options, based on an actual edgeworth expansion type density.
• pdfcdf.g Estimate risk neutral pdf,cdf,option deltas & gammas, based on d(i.v.)/Moneyness,etc.
• pdfmatch.g & pdfmatch.dec Estimate a parametric edgeworth expansion type density to match an empirically obtained density.
• parfit.g & parfit.dec Parametricly fit r.n. pdf, based on an edgeworth expansion type density.
