@bhargava-d16 Didn't get a chance to take an in-depth look. For now have left out a few comments!!

Suggested change

	double y;
	static double benchmark( void ) {
	double sigma[ 100 ];
	double mu[ 100 ];
	double x[ 100 ];
	double elapsed;
	double y;

Ordering by length

here this can optimized by utilizing the in-house utility of isAlmostSameValue from @stdlib/assert/is-almost-same-value.
Ref:-

stdlib/lib/node_modules/@stdlib/stats/base/dists/wald/pdf/test/test.pdf.js

Line 214 in 8336cd9

t.ok( isAlmostSameValue( y, expected[i], 1500 ), 'within tolerance. x: '+x[ i ]+'. mu: '+mu[i]+'. lambda: '+lambda[i]+'. y: '+y+'. E: '+expected[ i ]+'.' );

If you feel this adds more value do go ahead and update it in the other test files as well.

Let's sync this description documented here with the one used for the C implementation at main.c.
