Analysis of variance: SIG = 0.113 > The value of 0.05 is too high, so it is suggested to adjust (add more data).
3. Coefficient: sig is greater than 0.05, indicating that the influence of various factors is not significant.
This equation can't explain the problem, so take more data and adjust it several times to ensure that R is close to 1 and the sig value is within the acceptable confidence interval (B in the coefficient is the coefficient of each variable X in the equation).
