[h4 Description]
|
||
|
|
|
||
|
|
This function finds some uses in statistical distributions: it
|
||
|
|
computes the partial derivative with respect to /x/ of the incomplete
|
||
|
|
beta function __ibeta.
|
||
|
|
|
||
|
|
[equation derivative2]
|
||
|
|
|
||
|
|
The return type of this function is computed using the __arg_promotion_rules
|
||
|
|
when T1, T2 and T3 are different types.
|
||
|
|
|
||

|
|
[h4 Accuracy]
|
||
|
|
|
||
|
|
Almost identical to the incomplete beta function __ibeta.
|
||
|
|
|
||
|
|
[h4 Implementation]
|
||
|
|
|
||
|
|
This function just expose some of the internals of the incomplete
|
||
|
|
beta function __ibeta: refer to the documentation for that function
|
||
|
|
for more information.
