My formal education is in economics. My programming skills and computer knowledge are self-taught. I have an uncanny ability to find answers to questions outside my immediate expertise. I have a deep love of learning and I enjoy building / fixing all kinds of things -- software, computer hardware, engines, etc.

How is the GDP Deflator calculated in practice? I didn't search. I simply went to the uninsightful Wikipedia page chrisaycock linked to and looked at the "See Also", "References", and "External links" sections. The first reference contains the US calculation. |

How is the GDP Deflator calculated in practice? -1 for not doing a quick search first. Plus, I'm fairly certain each government's agency that calculates GDP provides some documentation on the underlying calculations. |

backtesting options strategies in R blotter is very stable, but quantstrat is not. blotter is accounting infrastructure, it isn't oriented toward any type of security. I'm currently working on adding options functionality to quantstrat. |

How to detect and adjust for stock splits? Don't do this. It's much better to use quantmod::adjustOHLC with Yahoo data. When use.Adjusted=FALSE (the default), the function pulls the split and dividend data from Yahoo and calculates the ratios manually. |

Stochastic modelling of derivatives on dividends This is very broad (you have at least 5 questions). You'd likely get (better) answers if you split this into 2-4 more specific questions. |

Multiple (linear) regression @Freddy: I didn't vote to close, but this is close to "Could someone help me develop a trading strategy?" and therefore some may deem it's off-topic according to the FAQ. |

Daily returns using adjusted close @Marcus: from looking at the entire history, it seems the 5/1 stock split was on 1994-06-20, not 2006-06-19. |

How to simulate one-minute bars data from one-day bars? @Quartz: not all scaling will change the first and last observations. You could calculate the line between the start and end points and shift all the observations above (below) that line by the required factor to reach the high (low) for the period. |
