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

    Why shouldn't I just ask the AI to calculate the p-value directly?

    Because Large Language Models generate text based on probability, not logic. They frequently hallucinate complex floating-point math. This engine forces the AI to use a real local calculator, producing exact results every single time.

  • 02

    Does it assume equal variances?

    For independent tests, it currently uses the standard Student's t-test which assumes equal variance. Paired and one-sample tests calculate their specific formulas independently.

  • 03

    What alpha level is used for significance interpretation?

    The engine automatically interprets significance using the standard alpha = 0.05 (95% confidence level). The exact p-value is always returned so you can apply any custom threshold.
