var quantile = require( '@stdlib/stats-base-dists-signrank-quantile' );
Evaluates the quantile function for the Wilcoxon signed rank test statistic with n
observations.
var y = quantile( 0.8, 5 );
// returns 11
y = quantile( 0.5, 3 );
// returns 3
If provided a probability p
outside the interval [0,1]
, the function returns NaN
.
var y = quantile( 1.9, 5 );
// returns NaN
y = quantile( -0.1, 5 );
// returns NaN
If provided NaN
as any argument, the function returns NaN
.
var y = quantile( NaN, 5 );
// returns NaN
y = quantile( 0.0, NaN);
// returns NaN
If not provided a positive integer for n
, the function returns NaN
.
var y = quantile( 0.4, -1.0 );
// returns NaN
y = quantile( 0.4, 3.7 );
// returns NaN
Returns a function for evaluating the quantile function of the Wilcoxon signed rank test statistic with n
observations.
var myQuantile = quantile.factory( 8 );
var y = myQuantile( 0.4 );
// returns 16
y = myQuantile( 1.0 );
// returns 36
