Case studies with Bayesian methods

## Hierarchical model for spelling performance

A [hierarchical model](01%20spelling/spelling.ipynb) for the `spelling` data from the study `D. Thissen, Steinberg, and Wainer` (1993)

## Multinomial logistic model for three-class classifition

A [multinomial logistic model](02%20iris/classification.ipynb) for the `iris` dataset (Fisher, 1936)

## Fourier analysis for time series

A [Fourier analysis model](03%20keeling/periodic.ipynb) for the Mauna Loa CO2 data (the `Keeling curve`)

## Time series modeling with heteroskedastic data

A [hierarchical time series model](04%20air-politution/air-polution.ipynb) with log-normal likelihood for air polution data in Skopje.

## Inference with weights on observed data

A [simple example using Potential](05%20weighted%20observations/potential-example.ipynb) for inference with data with weights

## Monotone dependency modeling

A [simple example using Dirichlet prior](06%20monotone/monotone-dirichlet.ipynb) for modeling of monotone dependency

## Slow evolving multiplicative factor - Covid-19 Rt model

A [model for estimation of the Rt reproductive factor for Covid-19](07%20covid19/simple-MK.ipynb), modeled with Random walks in the log scale.
