Hi Devon, try ‘stats’ add-on in Package Manager…
load 'stats/base/distribution'
load 'plot'
plot binomialdist 0.8 20
plot binomialdist 0.2 20

Has anyone plotted a binomial distribution in J? Either a histogram,
point, or line plot? I know there's something in R I can use but I'd like
to have a way to do it as well or better in J.
Thanks,
Devon

We are trying to do the same thing- where you concentrate on a point- slope
approach, I tend to a rotation of points -and there can be many- points on a
shape or a curve. With this latest example I use the following.
rotheta=:([:r.[)*]
pts=:_1j0 0j1 1j2
ctr=:_1j1
] s=:ctr+ (1r4p1) rotheta
Thanks; of course, and together with Ben Gorte's
suggestion delivers the wanted result:
] v=. 5+i.4
5 6 7 8
}: ,v ,.($v) # 1
5 1 6 1 7 1 8

There's nothing wrong with "normal order".
But you can go only so far, with words. At some point you need to
illustrate the concept.
Which brings up another problem: the 4 got chopped off the current
definition of z in that example:
]z=: 0 10 20 +/ i. NB. sample noun
Anyways, if you just s

Hui Sent: Thursday,
Trying to word the question which originally came to mind when I
looked at this problem (converting the "list notation" of a c.f.) to
a decimal value:
How would one go about throwing in the additional "1"s into the
spaces (gaps) of the paling fence..? (There is one less "1" compared
to the nu
To keep students organized in dealing with fractions I sometimes (on
a good day) have them work out intermediate results of continued
fractions like phi = [1; 1, 1, 1, ...] or sqrt(2) = [1; 2, 2, 2, ...].
This example I found at
http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/cfINT
Maybe... The new list interweaves the two original lists.
The "strategy" also applies to lists of numbers.
