[edit] Citation for Bliss

The citations for Bliss's papers are already in the article. I added McCullagh & Nelder which claims this was developed by Bliss. I thus then removed the cite needed tag. Baccyak4H (Yak!) 17:39, 11 June 2007 (UTC)

Where is the cite in M&N (i.e. what page?) Pdbailey 02:18, 12 June 2007 (UTC)

From the second edition (1989), top of pg 13 (beginning of section 1.2.5): "The technique known as probit analysis arose in conection with bioassay, and the modern method of analysis dates from Bliss (1935)." Baccyak4H (Yak!) 13:05, 12 June 2007 (UTC)

The same book (p 43) says that the method of solving the probit was in an appendix to the same article, written by Fisher. How can one be so sure that Fisher didn't influence Bliss? Pdbailey 13:10, 12 June 2007 (UTC)

I read that ref to imply Fisher's contribution was using the scoring method in the context of the model itself. However, without immediate access to the paper, that is just my best educated interpretation/guess. If reading the paper in its entirety suggests Fisher could get co-credit (or even most or all of the credit) for the model itself, this article should reflect that. If you an get a copy, that would be great. 17:50, 12 June 2007 (UTC)

[edit] X prime?

Is x prime correct? I've always seen it xB, not x'B for the classical linear model.Aaronchall (talk) 04:54, 8 January 2008 (UTC)
