This is likely due to how your tsconfig.json is configured and how TypeScript resolves CommonJS modules. It looks as if the CDF function is made available under the default property such that the below likely works for you as-is:

import cdf from "@stdlib/stats-base-dists-beta-cdf";

test("confidence", () => {
    cdf.default(0.5, 1, 2);
});

You should be able to change the esModuleInterop setting to get around this. Please have a look at the documentation for more information about why this happens:

https://www.typescriptlang.org/tsconfig#esModuleInterop

Please let us know if that doesn't resolve the issue.

Thanks for the quick response! Yep, including esModuleInterop in my tsconfig resolves the issue. Good to know this is the recommended solution for this environment.
