| Distribution name | Distribution variable | Notes |
|---|---|---|
| none | N/A | Uses the value as given. |
| uniform | half_range | mean is the median (middle) value, and half_range half the difference between the highest and lowest value. |
| normal | std_dev | Regular normal distribution. |
| uniform_relative | scale_factor | A normal distribution where the highest and lowest possible value are mean* (1+scale_factor) and mean* (1-scale_factor) respectively. Scale factor to be given as a decimal. |
| log_normal | std_dev | Regular log_nromal distribution. |
| weibull | k, scale_factor | Does not take a mean value. Equivalent to scale_factor*(-ln((U))1/a where U is the uniform distribution over [0, 1). |
| truncated_normal | std_dev, limit | Similar to normal distribution, except all values fall within [limit] standard deviations of the mean. |
A note on emod3d
Any variable found in the e3d.par file may be placed in the emod3d section of source_uncertainty.yaml, and will be carried over. Any non numeric entries must have the distribution 'none'.
