samplers allows you to sample from common distributions and calculate
summary statistics from the command line.
```shell ▶ samplers samplers Sample from common distributions and calculate summary statistics from the command line.
USAGE:
samplers
FLAGS: -h, --help Prints help information -V, --version Prints version information
SUBCOMMANDS: binomial Sample from a binomial distribution Bin(n, p) exponential Sample from an exponential distribution Exp(λ) gaussian Sample from a normal distribution 𝓝（μ, σ²） help Prints this message or the help of the given subcommand(s) histogram Displays a histogram of given values. mean Calculate the mean of given values. poisson Sample from a Poisson distribution Pois(λ) summarize Calculate basic summary statistics. uniform Sample from a uniform distribution Uniform(a, b) variance Calculate the variance of given values. ```
