Expand description
LogNormal Distribution Module containing functions to the log Normal Distribution.
Implemented by statrs::distribution::LogNormal.
The log Normal Distribution has two parameters:
μ: μ ∈ R (real numbers) σ: 0 < σ (rate)
Usage:
log_normal_pdf(x, μ, σ)
log_normal_ln_pdf(x, μ, σ)
log_normal_cdf(x, μ, σ)
log_normal_sf(x, μ, σ)
with
x: (-∞, +∞) Float64/DOUBLE,
μ: (-∞, +∞) Float64/DOUBLE,
σ: (0, +∞) Float64/DOUBLE
Examples
#[tokio::main(flavor = "current_thread")]
async fn main() -> std::io::Result<()> {
let mut ctx = datafusion::prelude::SessionContext::new();
datafusion_statrs::distribution::log_normal::register(&mut ctx)?;
ctx.sql("SELECT log_normal_pdf(1.1, 9.0, 1.0)").await?
.show().await?;
Ok(())
}
