Three Pairs Intercept Regression R Squared Calculator
Three Pairs Intercept Regression R Squared Calculator — Exactly three whole-number pairs; intercept model only, no confidence or general-model R-squared.
Exactly three whole-number pairs; intercept model only, no confidence or general-model R-squared. Calculations use finite-precision arithmetic.
Accepted inputs: X1 value: -1,000 to 1,000 number; X2 value: -1,000 to 1,000 number; X3 value: -1,000 to 1,000 number; Y1 value: -1,000 to 1,000 number; Y2 value: -1,000 to 1,000 number; Y3 value: -1,000 to 1,000 number.
How the calculation works
For one-predictor ordinary least squares with an intercept and nonconstant X and Y, R-squared is the squared Pearson correlation.
Worked example
With x1 value 1 number, x2 value 2 number, x3 value 4 number, y1 value 2 number, y2 value 5 number, y3 value 6 number, result is 0.793956044 number.
Assumptions and limits
Exactly three whole-number pairs; intercept model only, no confidence or general-model R-squared. Calculations use finite-precision arithmetic.
