auto stan::math::internal::conditionally_grad_sw ( F &&  functor, T_y &&  y_diff, T_a &&  a, T_v &&  v, T_w &&  w, T_sv &&  sv, T_sw &&  sw, T_err &&  log_error  )

inline

Helper function for agnostically calling wiener5 functions (to be integrated over) or directly calling wiener7 functions, accounting for the different number of arguments.

Specialisation for wiener5 functions

Template Parameters

GradSW	Whether the gradient of sw is computed
F	Type of Gradient/density functor
T_y	type of scalar variable
T_a	type of boundary separation
T_v	type of drift rate
T_w	type of relative starting point
T_sv	type of inter-trial variability in v
T_sw	type of inter-trial variability in w
T_err	type of log error tolerance

Parameters

functor	Gradient/density functor to apply
y_diff	A scalar variable; the reaction time in seconds without non-decision time
a	The boundary separation
v	The drift rate
w	The relative starting point
sv	The inter-trial variability of the drift rate
sw	The inter-trial variability of the relative starting point
log_error	The log error tolerance

Returns
