Discussion Overview
The discussion focuses on deriving the distribution of the sum of two circular uniform random variables (RVs) defined in the range [0, 2π). Participants explore the implications of the modulo operation on the sum and consider variations involving different distributions.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant seeks analytical steps for deriving the distribution of the sum of two circular uniform RVs modulo 2π.
- Another participant suggests a formula for calculating the probability distribution of the sum, indicating that it involves considering the ranges of the sums and applying the modulo operation.
- A different participant proposes a scenario where one RV is circular uniform and the other is uniform over a different range, questioning whether their sum remains uniform and expressing uncertainty about the resulting range.
- Concerns are raised about the clarity of whether the sum is to be considered modulo 2π, with references to conflicting definitions of the modulo operation found in external sources.
Areas of Agreement / Disagreement
Participants express uncertainty regarding the treatment of the modulo operation in the context of the sum of the RVs. There is no consensus on whether the sum remains uniform or how the ranges interact.
Contextual Notes
Participants note the ambiguity in definitions of the modulo operation, which may affect the interpretation of results. The discussion also highlights the complexity introduced by varying the distributions of the RVs.
