y is found increasing or decreasing with respect to x based on a Spearman correlation test.
Parameters: 


Returns: 

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.
