Two Parameter Weibull Probability Plot

Wednesday, 18 October 2023, 10.27

Unweighted constrained simplex regression

Gradient:  0.9724        s.e. 0.0118
Intercept: 0.189         s.e. 0.0739

Correlation Coefficient, r: 0.9783
Critical Value for r:       0.0485
Significance level used:    5.0%
Sum of squares:             151.3739

Best Estimates of the Parameters
sigma:  6.4847      'pseudo-linear' s.e. 0.0324
gamma:  2.451       'pseudo-linear' s.e. 0.0344

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