Flexible bandwidth selection methodsmedium

Supports robust fitting to handle outliersmedium

↓ Weaknesses

Limited language supporthigh

Loess.jl is primarily developed for Julia, which may limit its accessibility and utility for developers who are not familiar with or do not use the Julia programming language.

Complex setup processmedium

Setting up Loess.jl requires a working knowledge of the Julia package manager (Pkg) and potentially additional dependencies, which can be challenging for beginners or those unfamiliar with Julia's ecosystem.

Performance issues with large datasetshigh

Local regression algorithms like Loess.jl can become computationally expensive when applied to very large datasets, leading to slow performance and increased memory usage.
