The MAKELIST function can also be used to simulate observations on

random variables.

For example, suppose we wish to simulate 10

Bernoulli trials with p = 0.75. We can use the

fact that a test like (X<4) or (Y>0.2) returns a

value of either 1 (if the test is true) or 0 (if the

test is false).

Thus:

MAKELIST(RANDOM<0.75,X,1,10,1)

will return a list of 1’s and 0’s corresponding to the simulated Bernoulli trials.

Various examples of this process are given in the ‘Tips and Tricks’ section

which immediately follows the chapter on Univariate Statistics. See page

130.

LIST({list})

This function returns the product of all the elements of a list.

Eg. LIST({2,3,5}) would return a value of 30.

POS({list},num)

This function conducts a search of a list. It

returns the position in the list of the first

occurrence of the number you specify (see

example right). It is of more use to

programmers, who will not know in advance

what a list contains.

If the number specified is not in the list it returns zero. If the value occurs in

more than one place then only the first position is reported. The value

specified can be either a number (as shown) or a variable or an expression to

be evaluated.
