Function average 

pub fn average<T>(data: &[T]) -> StatsResult<f64>
where
    T: ToPrimitive + Debug,

Calculate the arithmetic mean (average) of a dataset.

The average is calculated as the sum of all values divided by the number of values.

Arguments

• data - A slice of numeric values implementing ToPrimitive

Returns

• StatsResult<f64> - The average as a f64, or an error if the input is invalid

Errors

Returns StatsError::EmptyData if the input slice is empty. Returns StatsError::ConversionError if any value cannot be converted to f64.

Examples

use rs_stats::prob::average;

// Calculate average of integers
let int_data = [1, 2, 3, 4, 5];
let avg = average(&int_data)?;
println!("Average of integers: {}", avg);

// Calculate average of floats
let float_data = [1.0, 2.5, 3.0, 4.5, 5.0];
let avg = average(&float_data)?;
println!("Average of floats: {}", avg);

// Handle empty input
let empty_data: &[i32] = &[];
assert!(average(empty_data).is_err());
