Hi, Could anybody explain "Implied Volatility" of a call or put Option? If we had to plot "implied volatility" versus Strike price, how would that plot look like (in the case of call and put option). If somebody has a program computing implied volatility (S-Plus, Matlab), please forward. Thank y

This is quite a silly problem. No wonder statistics (for business) gets so little respect. This is time series or process data--not a random sample from some fixed population. There is no information about the stability of the process over time. Very few business processes are stable over five yea

Dear junk, Such a task is indeed accomplished in Excel easily. You have to just remember that it's a spreadsheet, and there are certain ways that spreadsheets operate, and that's the key to the solution. I would tell you more, but it would be horrible if by doing so I facilitated a student's cheat
