Two Parameter Weibull Probability Plot

Thursday, 16 November 2023, 14.41

Unweighted constrained simplex regression

Gradient:  1.014         s.e. 0.0072
Intercept: -0.1007       s.e. 0.0459

Correlation Coefficient, r: 0.9919
Critical Value for r:       0.0352
Significance level used:    5.0%
Sum of squares:             159.8244

Best Estimates of the Parameters
sigma:  6.3335      'pseudo-linear' s.e. 0.0242
gamma:  1.9796      'pseudo-linear' s.e. 0.0163

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