Parameter estimates of the non-liner regression model describing the co-influence of temperature and relative humidity (RH) on the concentration levels of Pseudomonas amygdali pv. lachrymans (Pal) in aerosols.
| Parameter | Estimate | Standard error |
|---|---|---|
| Z0 | – 1425.03 | 1278.35 |
| a | 140.01 | 71.76 |
| b | – 12.81 | 19.37 |
| c | – 0.68 | 0.35 |
| d | – 2.13 | 1.28 |
| f | 0.31 | 0.11 |
The model is a six-parameter model: Z = Z0 + ax + by + cxy + dx2 + fy2. In the model, Z = the concentration of Pal aerosols, x = T, y = RH, Z0, a, b, c, d and f are parameters. In the non-liner regression model, reduced Chi-Sq is 48171.68, R-Square (COD) is 0.71, and Adj. R-Square is 0.67.
