GetRange() public method

Get range around median containing specified percentage of values.

The method calculates range of stochastic variable, which summary probability comprises the specified percentage of histogram's hits.

Sample usage:

 // create histogram ContinuousHistogram histogram = new ContinuousHistogram( new int[] { 0, 0, 8, 4, 2, 4, 7, 1, 0 }, new Range( 0.0f, 1.0f ) ); // get 50% range Range range = histogram.GetRange( 0.5f ); // show the range ([0.25, 0.75]) Console.WriteLine( "50% range = [" + range.Min + ", " + range.Max + "]" );

public GetRange ( float percent ) : AForge.Math.Range
percent	float	Values percentage around median.
return	AForge.Math.Range

        public Range GetRange( float percent )
        {
            int min, max, hits;
            int h = (int) ( total * ( percent + ( 1 - percent ) / 2 ) );
            int n = values.Length;
            int nM1 = n - 1;

            // skip left portion
            for ( min = 0, hits = total; min < n; min++ )
            {
                hits -= values[min];
                if ( hits < h )
                    break;
            }
            // skip right portion
            for ( max = nM1, hits = total; max >= 0; max-- )
            {
                hits -= values[max];
                if ( hits < h )
                    break;
            }
            // return range between left and right boundaries
            return new Range(
                ( (float) min / nM1 ) * range.Length + range.Min,
                ( (float) max / nM1 ) * range.Length + range.Min );
        }
