nls() fit to Kahnemann/ Tversky function
Dear WizaRds,
I would like to fit a curve to ten points with nls() for one
unknown parameter gamma in the Kahnemann/ Tversky function, but somehow
it won't work and I am unable to locate my mistake.
p.kum <- seq(0.1,1, by=0.1)
felt.prob.kum <- c(0.16, 0.23, 0.36, 0.49, 0.61, 0.71, 0.85, 0.89, 0.95,
1) ## how to find a function that fits these points nicely?
plot(p.kum, felt.prob.kum) ## looks a little like a...

New package: eba
I have recently uploaded a new package to CRAN called eba,
which stands for elimination-by-aspects models.
It allows for fitting and testing probabilistic choice models,
especially the BTL model (Bradley & Terry, 1952; Luce, 1959),
elimination-by-aspects (EBA) models (Tversky, 1972), and
preference tree (Pretree) models (Tversky & Sattath, 1979).
I believe that the functions in this package can be useful
in many fields, like marketing, consumer research, psychological
scaling, and food testing, to name only a few.

[patch] ssh-keygen(1): generate Ed25519 keys when invoked without arguments

re cognizing patterns
DeaRs,
i'm looking for some references on a statement as follows:
"Humans are good at spotting trends and patterns in data, but they are also
good at spotting those patterns where none really exist". This is not
verbatim but there must be some scholarly work on this. I can't remember
where I came across it - perhaps I dreamed it up? Help, anyone?
Best wishes
Paul

Rating competitors
I am looking for hints on how to estimate ratings for competitors
in an ongoing pairwise competition using R... my particular area of
interest being the game of Go, but the idea of identifying ratings
(on a continuous scale) rather than relative rankings seems easily
generalized to other competitions so I thought someone might be
studying something related already.
I presume the rating of a
