What is it that a statistician does? I threw on the careers tag. I think that fits somewhat. Also thinking this should be CW. |

What if interaction wipes out my direct effects in regression? If the v1:v2 interaction is not significant, do you need to have it included in the model? |

Good GUI for R suitable for a beginner wanting to learn programming in R? This is true. Another advantage to this is allowing beginners to see what parameters a function takes without using the ? command. Using FALSE instead of F is a great point. I once saw a program give an incorrect output because the programmer had earlier set the result of an ANOVA to a variable called "F". |

Good GUI for R suitable for a beginner wanting to learn programming in R? +1 for Rcmdr. It's nice for when one is just learning R, and offers more of a gateway to a good statistics package than SPSS or Minitab, but the code it writes is needlessly verbose, often. A scatterplot produced in Rcmdr: scatterplot(tab~pct, reg.line=FALSE, smooth=FALSE, spread=FALSE, boxplots=FALSE, span=0.5, data=senate.race), when most of those parameters were defaults to begin with. It writes some very wordy code. |

Most famous statisticians @Michael Lew: He certainly is. He managed to get over the supposed disconnection between Mendelian genetics and Darwinian evolution, among other accomplishments. digital.library.adelaide.edu.au/coll/special//fisher/9.pdf |

F-test for Lack-of-Fit in SPSS Your link seems like it explains it fairly well, gd. It's a little verbose, but it does the job. If you really feel most comfortable in R and need the output in SPSS, DrNexus' suggestion about the SPSS-R connection is sufficient. |

What are common statistical sins? @Michael: (+1). The Goodman article was especially insightful in supporting your argument. |

Internal reliability for an ordinal scale Not sure if this helps, but this article claims using Cronbach on ordinal data will underestimate the true value: amstat.org/meetings/jsm/2007/OnlineProgram/… |

What are common statistical sins? Perhaps I don't see why this is such a problem. Hypothesis testing a small sample size using a normal distribution, sure, but using a more conservative/nonparametric test, is this so bad? |

Regression Proof that the point of averages (x,y) lies on the estimated regression line The regression line is the line that minimizes the sum of squared errors. Knowing that, and a basic knowledge of calculus, find the values of B0 and B1 that minimize that sum of squared errors. The rest requires a little bit of high school level algebra. |
