    Mode

    NPM version Build Status Coverage Status dependencies

    Normal distribution mode.

    The mode for a normal random variable with mean μ and standard deviation σ > 0 is

    Mode for a normal distribution.

    Installation

    npm install @stdlib/stats-base-dists-normal-mode

    Usage

    var mode = require( '@stdlib/stats-base-dists-normal-mode' );

    mode( mu, sigma )

    Returns the mode for a normal distribution with parameters mu (mean) and sigma (standard deviation).

    var y = mode( 2.0, 1.0 );
    // returns 2.0
    
    y = mode( 0.0, 1.0 );
    // returns 0.0
    
    y = mode( -1.0, 4.0 );
    // returns -1.0

    If provided NaN as any argument, the function returns NaN.

    var y = mode( NaN, 1.0 );
    // returns NaN
    
    y = mode( 0.0, NaN );
    // returns NaN

    If provided sigma <= 0, the function returns NaN.

    var y = mode( 0.0, 0.0 );
    // returns NaN
    
    y = mode( 0.0, -1.0 );
    // returns NaN

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var mode = require( '@stdlib/stats-base-dists-normal-mode' );
    
    var sigma;
    var mu;
    var y;
    var i;
    
    for ( i = 0; i < 10; i++ ) {
        mu = ( randu()*10.0 ) - 5.0;
        sigma = randu() * 20.0;
        y = mode( mu, sigma );
        console.log( 'µ: %d, σ: %d, mode(X;µ,σ): %d', mu.toFixed( 4 ), sigma.toFixed( 4 ), y.toFixed( 4 ) );
    }
