...a set of physics-journal datasets and several higher-order theoretical equations that I need handled entirely in Python. The job is two-fold: first, deliver working code that plots line graphs, bar charts, and scatter plots drawn straight from the papers; second, build numerical routines that solve my higher-order equations with solid, peer-review-ready accuracy. I expect the core stack—NumPy, SciPy, and Matplotlib—to be used, and I’m happy for you to introduce any additional scientific libraries if they streamline the workflow or boost performance. All scripts or notebooks must be fully commented so I can trace every step later. Alongside the code, I want a short, hands-on learning component focused on the data-science aspects of Python: explanations of your ...

...be implemented, tested, and benchmarked in both Python and MATLAB. The core work involves translating existing mathematical formulations into efficient, well-documented code, validating the results against reference datasets, and profiling performance so the same algorithm behaves consistently across the two languages. Much of the heavy lifting will rely on standard scientific stacks—NumPy, SciPy, pandas, and matplotlib on the Python side, with equivalent functions and toolboxes in MATLAB—so fluency with these libraries is essential. I will provide the underlying equations, sample input files, and baseline outputs; the task is to turn those pieces into clean, reusable functions or class modules, then verify accuracy to at least six significant figures and demonstra...

My priority is to uncover how these variables relate to one another, so I need a thorough correlation study—Pearson where assumptions hold, and an alternative (e.g., Spearman) when they do not—alongside the classic descriptive stats: mean, standard deviation, and any other summary measures you believe add insight. You are free to work in the environment you prefer—Python (pandas, SciPy, seaborn), R (tidyverse, ggplot2), SPSS, Stata, or any other tool that lets you produce reproducible results. Visual clarity matters, so please include readable tables and at least one visual overview such as a correlation heat-map or scatter-matrix.
