# **`pammtools`**: Piece-Wise Exponential Additive Mixed Modeling Tools

### Installation

Install from CRAN or GitHub using:

```{r eval = FALSE}

# CRAN

install.packages("pammtools")

# Development version

remotes::install_github("adibender/pammtools")

```

### Overview

**`pammtools`** facilitates the estimation of Piece-wise exponential Additive Mixed Models (PAMMs) for time-to-event data. PAMMs can be represented as generalized additive models and can therefore be estimated using GAM software (e.g. **`mgcv`**), which, compared to other packages for survival analysis, often offers more flexibility w.r.t. to the specification of covariate effects (e.g. non-linear, time-varying effects, cumulative effects, etc.). The package supports single-event analysis, left-truncation, recurrent events, competing risks and multi-state models.
