| Jul 1, 2012 at 12:49 | comment | added | mljrg | @Macro: that's a good topic. Clearly not everything can be automated (I never meant that when I wrote above "tool that checks as much as possible the assumptions of a statistical test") but once I decided for a statistical test based on knowledge of the sampled data, probably some other assumptions could be checked automatically by the chosen test function in the package being used. | |

| Jun 30, 2012 at 17:45 | comment | added | Frank Harrell | I too wholeheartedly disagree with @mljrg . Two things explain why. First think of all the silly tests of normality that people do to justify the use of the $t$-test, assuming the test has a power of 1.0. Secondly, there will be wide disagreement among statisticians on the exact "rules" for "satisfying assumptions". | |
| Jun 30, 2012 at 9:46 | comment | added | mljrg | @ttnphns: I agree with "A statistician must reflect to himself about every decision made (why did I prefer this test not that)", but better practical assistance doing that would be extremelly helpful has the options can be very hard to decide. (See my comment below to Michael Chernick where I give a great example of that in software programming) | |
| Jun 30, 2012 at 9:17 | comment | added | ttnphns | mljrg: as a self-justifying policy and value, "making human lives easier" is a road to death caused by amusement. A statistician must reflect to himself about every decision made (why did I prefer this test not that). This reflection should have taste of bitterness because we seek for justification of basically free, equivocal choice. "Making live easier" is a trick to escape the bitterness. | |
| Jun 30, 2012 at 8:47 | comment | added | mljrg | Evolution is to move forward into supporting higher-level abstractions to make human lives easier (e.g., computer languages and handheld scientific calculators with lots of high-level functions), so I think those "deadly efforts" are welcome. (For example, being a programmer, I don't imagine going back to use assembly language.) Anyway, I think there should be support for the statistian who wants to control every analysis parameter, and also for those who occasionally need some statistical assessment. | |

Having some kind of decision support tree is always beneficial. But software designed to automatically check the assumptions, if it means "automatically choosing the most appropriate test" is a project for castrating a man mentally. Unfortunately, some otherwise respectible packages (e.g. SPSS) have already started deadly efforts in this direction.
