Credible intervals for Saturation Curves?

[steven-struglia]

Hi! Is there a way I could go about creating a credible interval of the saturation curves, something like [25,75] or [10,90] percentiles of the spend vs. response? I tried editing the code so that the prediction would also return the 25th and 75th percentile value along with the mean in plot_response_curves, but they seem to be very wrong. I was wondering if there's any plans to create this utility or if there's a way that someone knows how. Thanks in advance!
