Explore relative survival analysis in cancer studies through this conference talk at JuliaCon 2024. Delve into NetSurvival.jl, a Julia package designed to extract net survival curves from datasets lacking reliable cause-of-death information. Learn about the package's integration with the StatsModels.jl API, its implementation of standard estimators and routines, and its potential for extending existing modeling methods. Discover how NetSurvival.jl aims to provide a fast, reliable, and easily maintainable alternative to current R packages with C and C++ routines. Gain insights into the package's current state, implemented tools and methods, and their integration into the Julia ecosystem. Witness a showcase of the functionalities and performance of the implemented methods, highlighting the benefits of using native Julia for code concision and readability.
