Description
Interpret takes a vector or data.frame as argument. And returns a data.frame with certain textual inputs interpreted as probability distributions.
| Example | Regular expression | Interpretation |
|---|---|---|
| 12 000 | # # | 12000. Text is interpreted as number if space removal makes it a number. |
| -14,23 | -# | -14.23. Minus in the beginning of entry is interpreted as minus, not a sign for a range. |
| 50 - 125 | # - # | Uniform distribution between 50 and 125. |
| < 4 | < # | Uniform distribution between 0 and 4. |
| -12 345 - -23.56 | -# - -# | Uniform distribution between -12345 and -23.56. |
| 1 - 150 | # - # | Loguniform distribution between 1 and 150 (Loguniformity is assumed if the ratio of upper to lower is > 100) |
| 3.1 ± 1.2 or 3.1 +- 1.2 | # ± # or # +- # | Normal distribution with mean 3.1 and SD 1.2 |
| 2.4 (1.8 - 3.0) | # (# - #) | Normal distribution with mean 2.4 and 95 % confidence interval from 1.8 to 3.0 |
| 2.4 (2.0 - 3.2) | # (# - #) | Lognormal distribution with mean 2.4 and 95 % confidence interval from 2.0 to 3.0. Lognormality is assumed if the difference from mean to upper limit is => 50 % greater than from mean to lower limit. |
| 0:0.5:1 | #:#:# | Triangular distribution. Inputs are always sorted so order of arguments doesn't matter. |
