Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Bayesian A/B Calculator, so you can see the experience inside your AI.

It does not authenticate your account with Bayesian A/B Calculator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Bayesian A/B Calculator owners ask.

  • 01

    What does the superiority probability tell me?

    It tells you the likelihood that Variant B's conversion rate is higher than Variant A's, based on your observed data.

  • 02

    How do I use the decision recommendation capability?

    Provide your conversion and visitor counts for both variants. You can also set a confidenceThreshold (e.g., 0.95) to define how much certainty you require before the capability recommends choosing Variant B.

  • 03

    What is 'Expected Loss' in this context?

    Expected loss quantifies the potential downside risk. It represents the expected reduction in conversion rate if you choose a variant that is actually inferior to the other.
