### References verifying accuracy of R for basic statistical calculations and tests

Do you know of any references that verify the accuracy of R for basic statistical calculations and tests. The results of these studies should indicate that R results are the same as the results of other statistical packages to a certain number of decimal places on some benchmark calculations.

### [R] References verifying accuracy of R for basic statistical calculations and tests

Actually, you may not want R to agree so precisely with some of the packages since some well-known packages have some not-so-well-known inaccuracies.

### [R] References verifying accuracy of R for basic statistical calculations and tests

This might be a place to start: http://www.burns-stat.com/pages/Tutor/spreadsheet_addiction.html Among the references listed there are: Assessing the Reliability of Statistical Software: Part I by B. D. McCullough (1998) http://www.amstat.org/publications/tas/mccull-1.pdf Assessing the Reliability of Statistical Software: Part II by B. D. McCullough (1999) http://www.amstat.org/publications/tas/mccull.pdf Those might have some relevance Then, doing within an R session: > RSiteSearch("Assessing Reliability Statistical Software") turns up 14 hits, many of them looking relevant [leaving "the" and "of" in the query results in the search engine timing out - odd?] -- Tony Plate Corey Powell wrote:> Do you know of any references that verify the accuracy of R for basic statistical calculations and tests.
