|
Returns the tail of the standard normal distribution at z.
|
|
Returns the significance level for the t test. If the value returned by t_test() is low, then the probability is large that t is high. |
|
Returns the significance level for the test that the F ratio is larger than 1.0. If the value returned by F_test() is low, then the probability is large that F is high. |
|
Returns the significance level for the test that the Chi2 is exceeded for a correct model. The less the probability, the better. :-) |
|
Returns the Q probability value for the Studentized Range. df is the degrees of freedom, kno is the number of groups. |
|
The regularized incomplete beta function.
|
|
The regularized incomplete gamma function (1/Gamma(a))*INTEGRAL[exp(-t)*t^(a-1) dt, 0, x].
