### Monotonic splines in Python [closed]

I am trying to find a procedure to fit data monotonically in Python. The data won’t be necessarily monotonic. I just would like to achieve a monotonic fit because of theoretical assumptions. I ...

### How do you apply constrains on parameters in Bayesian modeling?

In Frequentist modeling, I know how to fit and interpret models with constraints on the parameter space. Let's say I'm fitting a $N(\mu, \sigma^2)$ distribution to my data $x_1, \dots, x_n$, and I ...

### Linear regression of higher order polynomial with slope constraint

I am trying to constrain the coefficients on a higher order polynomial (let's say an order 6) for the curve to be decreasing. I have found this link, where the fitting of a 3rd order polynomial is ...

I have a data where several groups exist: $i = 1, 2, 3...n$ ($n$ about 600 groups in total). For group $i$ theory predicts a linear relation $y = a_i + b_i * x$ with $a_i$ and $b_i$ intercept and ...
