Action

Generate Random Numbers

1. Size: Set the number of samples extracted from the generated distribution.

2. Random State: Set the seed.

3. Allocate to: Specify the variable (call name) toate.

4. Show Sampled Distribution: Visualize the distribution drawn from the samples.

Show Distribution Plot

1. Probability Density Function: Output the probability density function.

2. Cumulative Distribution Function: Output the cumulative distribution function.

Statistics to P-Value

1. Statistic: You will obtain the probability of getting a value equal to or greater than the absolute value entered here in this distribution.

2. Alternative: Two-sided; for a two-tailed test, One-sided; for a one-tailed test.

P-Value to Statistics

1. Proportional Value: Enter the p-value; the range on the distribution where values equal to or greater than the entered p-value will be calculated and displayed.

2. Alternative: Choose between two-sided or one-sided test.

Discrete Probability Distribution

Bernoulli

1. P: Enter the probability of getting 1 in the binary outcome of 0 and 1.

2. User Option: Optionally provide additional desired options.

Binomial and Multinomial

1. N: Enter the number of trials.

2. P: Enter the probability of success in a trial. Use the Funnel Icon to fetch values entered in a specific dataframe column. (The form of the input values can be referred to in the generated examples.)

Continuous Probability Distribution

Normal

1. Loc: Set the mean of the normal distribution.

2. Scale: Set the standard deviation of the normal distribution.

3. User Option: Optionally provide additional desired options.

Beta

1. A: Set the shape parameter a of the beta distribution.

2. B: Set the shape parameter b of the beta distribution.

3. User Option: Optionally provide additional desired options.

Gamma

1. A: Set the shape parameter of the gamma distribution.

2. User Option: Optionally provide additional desired options.

Student's t and Chi2

1. Df: Set the degrees of freedom for the t-distribution or chi-squared distribution.

2. User Option: Optionally provide additional desired options.

F

1. Dfn: Set the numerator degrees of freedom.

2. Dfd: Set the denominator degrees of freedom.

• The F-distribution represents the ratio of two chi-squared distributions. Dfn and Dfd are the degrees of freedom for the two chi-squared distributions.

3. User Option: Optionally provide additional desired options.

Dirichlet

1. Alpha: Enter the importance for three categories (or dimensions) in the format (a, b, c).

2. Seed: If provided, the generated random numbers will be fixed.

3. User Option: Optionally provide additional desired options.

Multivariate Normal

1. Mean: Set the mean of the distribution. For [a, b], the mean of the first distribution is a, and the mean of the second distribution is b.

2. Cov: Set the covariance of the distribution. For [a, b], the covariance of the first distribution is a, and the covariance of the second distribution is b.

3. Allow Singular: If True, allows generating the distribution even when the covariance matrix is singular.

4. User Option: Optionally provide additional desired options.
