Furthermore, even if it were better phrased it would not be a question about R, but about statistics (sometimes tolerated here, but not appropriate). Finally, it sounds like a homework question (also inappropriate). Please read the posting guide ... sincerely Ben Bolker

The only statistical method that I know of that can be applied to any dataset without further definition of the nature of the data or the question being asked is SnowsCorrectlySizedButOtherwiseUselessTestOfAnything which is found in the TeachingDemos package for R. However this test is not common (for a couple of very good reasons). If you want a more useful method you first need to decide on what your question is that you want answered and have some more detail about the dataset. -----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf Of Ramnath R Sent: Monday, May 23, 2011 12:12 PM To: r-help at r-project.org Subject: [R] What are the common Standard Statistical methods used for the analysis of a dataset Hi, Anybody know what are the common Standard statistical methods used for the analysis of a dataset,and anybody know which of these methods give similar results Ram [[alternative HTML version deleted]] ______________________________________________ R-help at r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

He invented it. However, he never published it, preferring to communicate it by causing others to feel its impact whenever he writes anything.

[R] What are the common Standard Statistical methods used for the analysis of a dataset
How can anyone overlook the intra-ocular trauma test (or sometimes called the inter-ocular concussion test). But the i-o trauma test needs either a small data set or an appropriate graph of the data (or can you look at a dataset of a hundred columns and a million rows and do an intra-ocular trauma test?). We were not told the size of the dataset or enough information to know what type of graph to make. You do make a good point though that with minimal additional information the intra-ocular trauma test can be useful (well if it is significant, there are many datasets that fail the intra-ocular trauma test, but still yield interesting results after careful study). And for any dataset that has a significant intra-ocular trauma test result, that should trump the results of SnowsCorrectlySizedButOtherwiseUselessTestOfAnything. -- Gregory (Greg) L.

Dear all, may I suggest the acronym IOTT for the inter-ocular trauma test? Now we just need someone to implement iot.test(). I assume it will appear on CRAN within the next 24 hours. Looking forward to yet another base package, Stephan Am 25.05.2011 23:36, schrieb Greg Snow:> How can anyone overlook the intra-ocular trauma test (or sometimes > called the inter-ocular concussion test).
