Two Parameter Weibull Probability Plot

Monday, 27 May 2024, 14.44

Unweighted constrained simplex regression

Gradient:  1.0491        s.e. 0.0227
Intercept: -0.4655       s.e. 0.1925

Correlation Coefficient, r: 0.9531
Critical Value for r:       0.1422
Significance level used:    5.0%
Sum of squares:             104.9815

Best Estimates of the Parameters
sigma:  8.5755      'pseudo-linear' s.e. 0.0954
gamma:  2.0737      'pseudo-linear' s.e. 0.0514

The 'pseudo-linear' s.e.s are a lower limit to the s.e. and may significantly underestimate the s.e.
