template<typename T , typename M , typename S , require_all_prim_or_rev_kernel_expression_t< T, M, S > * = nullptr, require_any_not_stan_scalar_t< T, M, S > * = nullptr, require_any_var_t< T, M, S > * = nullptr>

inline

Return the linearly transformed value for the specified unconstrained input and specified offset and multiplier.

The transform applied is

\(f(x) = mu + sigma * x\)

where mu is the offset and sigma is the multiplier.

If the offset is zero and the multiplier is one this reduces to identity_constrain(x).

Template Parameters

T	type of unconstrained input
M	type of offset
S	type of multiplier

Parameters

[in]	A	Unconstrained input
[in]	mu	offset of constrained output
[in]	sigma	multiplier of constrained output
[in,out]	lp	Reference to log probability to increment.

Returns

linear transformed value corresponding to inputs

Exceptions

std::domain_error	if sigma <= 0
std::domain_error	if mu is not finite
