Soon [MetidaBioeq.jl](https://github.com/PharmCat/MetidaBioeq.jl) will be in registry. This is a first release and it support only basic bioequivalence estimation in accordance with:

- EMA: [GUIDELINE ON THE INVESTIGATION OF BIOEQUIVALENCE](https://www.ema.europa.eu/en/documents/scientific-guideline/guideline-investigation-bioequivalence-rev1_en.pdf)

- EMA: [GUIDELINE ON THE INVESTIGATION OF BIOEQUIVALENCE, Annex I](https://www.ema.europa.eu/en/documents/other/31-annex-i-statistical-analysis-methods-compatible-ema-bioequivalence-guideline_en.pdf)

- FDA: [Guidance for Industry Statistical Approaches to Establishing Bioequivalence](https://www.fda.gov/media/70958/download)

Package include method `bioequivalence` that create BE structure with dataset and check it, and method `result` that make estimation (with GLM, MixedModels or Metida).

Version `0.1.0` not support adaptive design and reference scaling (it can be done manually). Also not included post-hoc power calculation, CV estimation and type III table (ANOVA/F-test) estimation - this is goals for further updates.

Validation with reference datasets and integration with MetidaNCA also in plans.

After all basic features will be included automatic report module can be started.

See [documentation](https://pharmcat.github.io/MetidaBioeq.jl/dev/). Don’t hesitate to make issues on github.

### Requirements

- Julia ≥1.8+
- MixedModels ≥4.11
- GLM ≥1.8.2
- Metida ≥0.14.6

### To install just now from main brunch

```julia-auto
import Pkg
Pkg.add(url = "https://github.com/PharmCat/MetidaBioeq.jl.git")

```
