Suggested change

	x[ i ] = uniform( mu[ i ], 50.0 );
	x[ i ] = uniform( mu[ i ], 100.0 );

[anandkaranubc]

The range should remain the same as original. This also applies throughout the PR.

[anandkaranubc]

Suggested change

	x[ i ] = uniform( -4.0, 4.0 );
	x[ i ] = uniform( 0.0, 4.0 );

Same comment as above.

[anandkaranubc]

Suggested change

	mu[ i ] = ( uniform( -50.0, 50.0 ) );
	mu[ i ] = uniform( EPS, 10.0 );

No need of outside brackets.

[anandkaranubc]

Same comment as above.

[hemantmm]

for this c[ i ] = ( uniform( EPS, 20.0 ) ); i have to make the changes as EPS,10.0?

[anandkaranubc]

Suggested change

	if ( dist.c !== y[ i % len] ) {
	if ( dist.c !== y[ i % len ] ) {

[anandkaranubc]

Suggested change

	x[ i ] = uniform( EPS, 100.0 );
	x[ i ] = uniform( 1.0 + EPS, 100.0 );

@hemantmm, thanks for raising a PR for this issue. I have left a few comments that need to be addressed. These comments apply throughout the PR, including areas where they were not explicitly mentioned.

Additionally, please review this discussion comment: #4993 (comment) and incorporate the suggested changes as well.

Also, the title should be updated to (for consistency):

bench: refactor random number generation in stats/base/dists/levy

(Note: The backticks should be included around stats/base/dists/levy.)

Good luck!
