Refactor Benchmarking for Pareto Type I Distribution

Description

This PR refactors the benchmarking code for the stats/base/dists/pareto-type1 module to improve accuracy and performance measurements.

Changes:

  • Replaced randu() with uniform() for more precise random number generation.
  • Moved random number generation outside the benchmarking loop to reduce overhead.
  • Ensured uniform() is correctly imported from @stdlib/random/base/uniform.

Issue

Fix #4988.

Testing

  • Verified benchmarks run correctly.
  • Ensured results are consistent and performance is improved.

Checklist

  • Code changes follow the project’s style guide.
  • Changes were tested and validated.
  • Related issue is linked.

Suggested change
var alpha = uniform( EPS, 100.0 );
var beta = uniform( EPS, 100.0 );
var alpha;
var beta;

Variable declarations happen at the top and separately from their initializations.

The use of uniform should be moved out of the benchmarking loop so it doesn't interfere with the benchmark results.

Hii @Mohammad-Tamerr,

I just had a look. I suggest reviewing the reference PR first to get a clearer understanding of how to approach this issue. There are some major changes that need to be made.

Thank you for working on this pull request. However, we cannot accept your contribution as this pull request does not follow project conventions.

We place a high value on consistency throughout the stdlib codebase, and this pull request was found to significantly deviate from stdlib conventions. We encourage you to closely examine other packages in stdlib and attempt to emulate the practices and conventions found therein.

  • If you are attempting to contribute a new package, sometimes the best approach is to simply copy the contents of an existing package and then modify the minimum amount necessary to implement the feature (e.g., changing descriptions, parameter names, and implementation).
  • If you are contributing tests, find a package implementing a similar feature and emulate the tests of that package.
  • If you are updating documentation, examine several similar packages and emulate the content, style, and prose of those packages.

In short, the more effort you put in to ensure that your contribution looks and feels like stdlib—including variables names, bracket spacing, line breaks, etc—the more likely that your contribution will be reviewed and ultimately accepted. We encourage you to closely study the codebase before continuing to work on this pull request.

Thank you again for your interest in stdlib, and we look forward to reviewing your future contributions.
