Hi,

I am having difficulty understanding this new function. When I read the starting statement "The GEN-TENDENCY function generates N samples of given values (floating  numbers)..." I thought, the function will generate N samples from the given list, but it does not do that! It does not directly generate from the "given values". Perhaps it will be of help if the explanation can be elaborated a bit more. For example, what does this do?

(gen-tendency 2 '(0.9 0.1 0.7 0.9))

 On my system, it gives => (0.917174 0.100803904)

 

I immediately thought it will generate two values closest to what is in the given list, but the following proved me wrong.

(gen-tendency 4 '(0.9 0.1 0.7 0.9)) => (0.90942806 0.09511808 0.09851663 0.68883634)

 

Can you explain the behaviour in greater detail? As a beginner, I am not able to relate the generated output with "tendency" argument.

 

Regards,

Rangarajan

This is correct. With 2 you get the first two values with the fluctuation of the variance.

This is a bug and will be fixed in the next update.

Version 1.1.18269 fixed the bug.

(gen-tendency 4 '(0.1 0.4 0.1 0.6 0.45 0.16 0.75 0.8 1.0 0.01))
=> (0.104359165 0.39429432 0.100798346 0.62476647)

 

The keyword :list t

List size:

(mapcar #'length (gen-tendency 200 '(.1 .4 .1 .6 .45 .16 .75 .8 .3 .1 .3) :list t))
=> (20 20 20 20 20 20 20 20 20 20)

 

Each given value will generate a list of 20 tendency's values.

N: = 200
values: (-1 11) = 10
(/ 200 10) = 20

I hope this clarifies the keyword :list t
