# DistUV

Dart library to sample univariate random distributions and calculate its statistics.

- [X] Beta

- [X] Binomial

- [X] Cauchy

- [X] Chi-Square

- [X] Exponential

- [X] Gamma

- [X] Geometric

- [X] Normal

- [ ] Pareto

- [X] Student's T

- [X] Uniform

- [ ] Weibull

- [ ] Beta

- [ ] Logistic

- [ ] Log-Normal

- [ ] F

- [ ] Laplace

# Usage

## Statistics of a distribution

```dart

  final beta = Beta(2.31, 0.627);

  print(beta.ppf(0.0));

```

## Sample random number from normal distribution

```dart

  for (int i = 0; i < 100; i++) print(randn);

```

## Sample random number from custom normal distribution

```dart

  final randnCust = normal(loc: 0.5);

  for (int i = 0; i < 100; i++) print(randnCust);

```
