 sklearn.isotonic.check_increasing   sklearn.isotonic.check_increasing(x, y)[source]
 
Determine whether y is monotonically correlated with x. y is found increasing or decreasing with respect to x based on a Spearman correlation test.  Parameters:
 
 
xarray-like of shape (n_samples,)


Training data.  
yarray-like of shape (n_samples,)


Training target.    Returns:
 
 
increasing_boolboolean


Whether the relationship is increasing or decreasing.     Notes The Spearman correlation coefficient is estimated from the data, and the sign of the resulting estimate is used as the result. In the event that the 95% confidence interval based on Fisher transform spans zero, a warning is raised. References Fisher transformation.
