Method Detail

cumulative

public static final double cumulative(double is,
                int n,
                boolean lower_tail)

Spearman exact cumulative distribution function for n <= 22. For n > 22, cumulative_as89 is invoked. Taken from pspearman package.

Parameters:

is -

n -

lower_tail -

Returns:

cumulative_as89

public static final double cumulative_as89(double is,
                     int n,
                     boolean lower_tail)

Spearman cumulative distribution. (taken from src/library/stats/src/prho.c) Algorithm AS89 -- actually an approximation

Parameters:

is -

n -

lower_tail -

Returns:

cumulative_t

public static final double cumulative_t(double is,
                  int n,
                  boolean lower_tail)

Spearman cumulative distribution function, approximation using T (df=n-2)

Parameters:

is -

n -

lower_tail -

Returns:
