Function h1 

Source 
pub fn h1(
    r: usize,
    theta: f64,
    info: f64,
    a: f64,
    b: f64,
) -> Result<DensityGrid, IntegrationError>
Expand description

Initialize the density grid for the first group sequential analysis.

§Errors

Returns IntegrationError::NonPositiveInformation when info is not strictly positive or propagates any IntegrationError from gridpts.

§Examples

use gsdesign::{h1, IntegrationError};

let grid = h1(5, 0.5, 2.0, -2.0, 2.0)?;
assert_eq!(grid.points.len(), grid.values.len());
assert!(grid.values.iter().all(|v| *v >= 0.0));
