confidence intervals
Hi David, Thank you for your comments, and feed-back message. I am very happy to learn from the experience of the people on R mailing list, and without any doubt, I am very thankful to you and to everyone for sharing their knowledge. I do apologize for any confusion that I have created unwillingly with my previous email. About my previous email related to the confidence intervals: indeed I have posted the question with a detailed description on stackoverflow, and the link is listed below. I have to admit that I have been in rush willing to have the suggestions of R-help members by Monday (if that would have been possible), as I have to make a decision at the beginning of this week on whether I need to re-code the shell script in R. I have a deadline on Wed. The script itself is less important per se, I have included it just to point our the origin of my question. I do certainly respect the principles of online R-help community, and I would very much appreciate if I could have your advice on the following : shall a "R code related emergency" arise, would it be acceptable to post the question on stackoverflow with the corresponding data tables and detailed code, and to refer the posting on R-help mailing list ? If it is acceptable at least for a single email, and if you do not mind, I could mention the link to stackoverflow, inviting our members to read it, shall they be comfortable with this topic. https://stackoverflow.com/questions/73507697/confidence-intervals-of-a-biological-assay?noredirect=1#comment129816241_73507697 Thanks a lot, have a good week ! ~ Bogdan https://stackoverflow.com/questions/73507697/confidence-intervals-of-a-biological-assay?noredirect=1#comment129816241_73507697 On Sat, Aug 27, 2022, 6:52 PM David Winsemius <dwinsemius at comcast.net> wrote:
You cross-posted this to StackOverflow and did not say so. ... and you posted in HTML Bad dog squared. I cast one of the close votes on SO, but here I can only say ... READ the Posting Guide. You also give no citation other than someone's Github files with minimal comments in that material. You should indicate whether this code has any solid support. Why do you think this code is something to depend upon? After all, you been posting questions on R-help for several months. Don't you think you should make a good faith effort to understand the principles underlying this resource? -- David. On 8/26/22 17:55, Bogdan Tanasa wrote:
Dear all, Although I know that it is not a statistics mailing list, given my work
on
ICeChIP
I would appreciate to have the answer to a question :
given two variables a and b (a and b can have 1000 paired-values) and a
calibration number "cal",
why the 95 confidence interval has been calculated as such for each value
a(i) and b(i) :
100 / cal * sqrt (( a/ (b^2) + (a^2) / (b ^3)) * 1.96
Thank you,
Bogdan
