Preview access · not provider authentication

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

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

FAQ

Questions jstat owners ask.

  • 01

    What is a contingency table?

    It's a matrix showing the frequency distribution of two categorical variables (e.g., rows = Gender, columns = Subscription Tier). The AI will automatically convert your raw data into this format.

  • 02

    Does it handle expected frequencies below 5?

    The engine computes the result regardless, but the AI is instructed to warn you when expected frequencies are low, as the chi² approximation becomes less reliable in those cases.

  • 03

    Can it test more than two variables at once?

    This engine performs a single pairwise independence test per execution. For multi-variable analysis, the AI can chain multiple calls to test different variable pairs sequentially.
