How this service works
R Squared
Output
Returns the R-squared (coefficient of determination) value, a number between 0 and 1 (or negative if the model is worse than a horizontal baseline) indicating how well the model explains variance in the dependent variable.
Example use cases
Regression model goodness-of-fit check
“I just ran a linear regression and got these observed and predicted values — can you compute the R-squared so I know how well the model fits?”
ML model evaluation in a pipeline
“As part of evaluating my machine learning model, calculate the R-squared score between the actual sales figures and the model's predictions for last quarter.”
Statistical reporting for a school project
“I need the coefficient of determination (R-squared) for my statistics homework — my observed values are [10, 20, 30] and predicted are [12, 19, 31]. Can you get that for me?”
Technical details
Endpoint
GEThttps://minia2a.uk/x402/rSquared?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call R-squared computation without setting up a local statistical library or data science environment. Ideal for lightweight agent workflows that need a single statistical metric on demand.
Side effects
- Missing or malformed input data arrays returns an error
- Mismatched lengths between observed and predicted arrays may cause a computation error
- Non-numeric values in input arrays will likely result in a failure response
- Empty input arrays may return an error or undefined result
