RANDOMNUMBERGENERATION()


    • RANDOMNUMBERGENERATION(), creates a number of several types of random numbers including Uniform, Normal, Bernoulli, Poisson, Patterned and Discrete.


Description

1)RANDOM NUMBER GENERATION - UNIFORM

  • Uniform Distribution is a distribution of a random variable in which each value has the same probability of occurrence.

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Uniform",NewTableFlag,MinNum,MaxNum)

2)RANDOM NUMBER GENERATION - NORMAL

  • A Normal Distribution is a type of distribution that plots all of its values in a symmetrical fashion and most of the results are situated around the probability's mean.

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Normal",NewTableFlag,Mean,StandardDeviation)

3)RANDOM NUMBER GENERATION - BERNOULLI

  • A theoretical distribution of the number of successes in a finite set of independent trials with a constant probability of success is called Bernoulli Distribution.

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Bernoulli",NewTableFlag,ProbabilityValue)

4)RANDOM NUMBER GENERATION - BINOMIAL

  • A Binomial Distribution is a frequency distribution of the possible number of successful outcomes in a given number of trials in each of which there is the same probability of success.

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Binomial",NewTableFlag,ProbabilityValue,NumTrials)

5)RANDOM NUMBER GENERATION - POISSON

  • A Poisson Distribution is a discrete frequency distribution that gives the probability of a number of independent events occurring in a fixed time. Poisson distribution can be applied to systems with a large number of possible events.

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Poisson",NewTableFlag,Lambda)

6)RANDOM NUMBER GENERATION - PATTERENED

  • A Patterned Distribution is a distribution of random occurrences in which one occurrence has repeating number and sequence in between the start and the end numbers.

RANDOMNUMBERGENERATION(NumVariable,RandomNumber,"Patterened",NewTableFlag,FromNum,ToNum,StepSize,NumRep,SeqRep)

7)RANDOM NUMBER GENERATION - DISCRETE

  • A discrete distribution is a distribution of a random variable that takes only finite set of values.
