RANDOMNUMBERGENERATION(NumVariable,RandomNumber,Distribution,NewTableFlag,ValueArr,Probability)

where,

• $NumVariable$ represents the number of columns for displaying the random numbers,
• $RandomNumber$ represents the number of rows for displaying the random numbers,
• $Distribution$ is the distribution method (i.e. "Discrete") for creating random values,
• $NewTableFlag$ is the flag TRUE or FALSE.
• $ValueArr$ represents the array of values,
• $Probability$ are the probability values between 0 to 1.

DISCRETE RANDOMNUMBERGENERATION() is used to display the random numbers within finite range.

Description

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Discrete",ValueArr,Probability)

• A discrete distribution is a distribution of a random variable that takes only finite set of values.
• If $NewTableFlag$ is TRUE, the result is displayed on new zspace.
• If $NewTableFlag$ is FALSE, the result is displayed on the same zcube. If omitted, it is assumed to be FALSE.
• If $NumVariable$ <0 or $RandomNumber$ <0, Calci displays an error message.
• If $Probability$ <0 or $Probability$ >1, Calci displays an error message.
• The addition of all probability values should be equal to '1'. Else Calci displays an error message.

Examples

=RANDOMNUMBERGENERATION(3,4,"Discrete",TRUE,[4,5,6,3,2,1],[0.2,0.1,0.3,0.2,0.1,0.1])

The above command displays the random numbers from the ValueArr with the respective probabilities in 3 columns and 4 rows in a separate zspace as -

3	1	3
4	4	6
3	6	6
1	3	3

=RANDOMNUMBERGENERATION(2,5,"Discrete",TRUE,[10,11,10.5],[0.4,0.4,0.2])

The above command displays the random numbers from the ValueArr with the respective probabilities in 2 columns and 5 rows in the same zspace as command -

10	11
11	10
10.5	11
10.5	11
10	11
