How do you find causal relationships in data? Causation is just not something you can squeeze from the numbers... so, repeat after me: causation is not correlation, causation is not correlation... |

Why not approach classification through regression? I voted to migrate to CV; I think it stands a better chance of getting answered there than here. |

What algorithm is used in linear regression? If you read this old book, you should also be looking into Åke Björck's Numerical Methods for Least Squares Problems, which has stuff not discussed in Lawson/Hanson. The routines included in the Lawson/Hanson book are available from Netlib. |

Reporting results of simple linear regression: what information to include? "Are there hard-and-fast rules for how much information to report" - it really depends on what you want to do after the regression. One might be happy with just the correlation coefficient; one might need the Durbin-Watson value on top of that, and still another one might want to see the diagonal of the hat matrix... it really depends. |

Chi-square test for checking if values are close to zero? Yes it does. Which means more work for you to do, i.e. a test for normality. Otherwise, I'm no longer up to date with what they use when the errors are non-normal. |

Chi-square test for checking if values are close to zero? I think you're supposed to do a $t$-test, not a $\chi^2$-test. See this. |
