I am trying to do a nonlinear regression, but I need to bound
(constrain) the parameters. For example,

NonlinearRegress[Data, a + b * Exp[-(x-c)/d], {x}, {a, b, c, d}]

The b in this case, I know must be between 1 and 1000, and the c
between 0.1 and 10. This is simply because of the physics of the

Is there a way to force NonlinearRegress to constrain the parameters
to some range, as in this example?
