| AIC | Exponential | 6252.84 | 6254.84 | 6252.84 |
| Weibull | 2915.84 | 2873.45 | 2869.56 | |
| Log-logistic | 3043.70 | 3045.70 | 3043.70 | |
| Log-normal | 3140.41 | 3142.41 | 3140.41 | |
| BIC | Exponential | 6306.57 | 6314.54 | 6306.57 |
| Weibull | 2975.53 | 2939.11 | 2935.23 | |
| Log-logistic | 3103.4 | 3111.37 | 3103.4 | |
| Log-normal | 3200.11 | 3208.08 | 3200.11 | |
NB: AIC = akaike information criteria and BIC = bayesian information criteria
