Example

Operation

 

 

RanNorm# (8, 68)

*(E)(PROB)*(RAND)(Norm)

(Randomly produces a body length value

8 68U

obtained in accordance with the normal

 

distribution of a group of infants less than

 

one year old with a mean body length of

 

68cm and standard deviation of 8.)

 

RanNorm# (8, 68, 5)

*(E)(PROB)*(RAND)(Norm)

(Randomly produces the body lengths of five

8 68 5U

infants in the above example, and displays

 

them in a list.)

SRandom Number Generation in Accordance with Binomial Distribution (RanBin#)

This function generates random integers in accordance with binomial distribution based on values specified for the number of trials n and probability p.

RanBin# (n, p [,m]) 1 n 100000 1 m 999 0 p 1

Omitting a value for m returns a generated random number as-is. Specifying a value for m returns the specified number of random values in list form.

Example

Operation

 

 

RanBin# (5, 0.5)

*(E)(PROB)*(RAND)(Bin)

(Randomly produces the number of heads

5 0.5U

that can be expected in accordance with

 

binomial distribution for five coin tosses

 

where the probability of heads is 0.5.)

 

RanBin# (5, 0.5, 3)

*(E)(PROB)*(RAND)(Bin)

(Performs the same coin toss sequence

5 0.5 3U

described above three times and displays

 

the results in a list.)
