Module Tests.Sign

module Sign: sig .. end

val one_sample : float array ->
       ?shift:float ->
       ?alternative:Tests.test_alternative -> unit -> Tests.test_result

Sign test, which evaluates the null hypothesis that sample median is equal to the specified shift.

Test assumptions:

1. Sample under test was randomly selected from the population it represents.

val two_sample_paired : float array ->
       float array ->
       ?alternative:Tests.test_alternative -> unit -> Tests.test_result

Dependent samples sign test, which evaluates the null hypothesis that the median difference between observations from two related samples is zero.

Test assumptions:

1. Samples under test were randomly selected from the population they represent.
