4.6.4. Paths Equations

As seen below, Equations (11)–(15) are the path equations for prediction of the agriculture production indexes and weather extremes.

Let *X*1 = Extreme Maximum Rainfall, *X*2 = Extreme Maximum Temperature *X*3 = Extreme Minimum Temperature

Thus, obtained are the following regression models for indexes prediction


$$\text{Crop production index} = -0.189 \text{ MaxRatio} + 0.206 \text{ MaxTemp} + 0.482 \text{ MinTemp} \tag{12}$$

*Cereal production index* = −0.266 *MaxRain* + 0.276 *MaxTemp* + 0.455 *MinTemp* (13)

$$\text{Cooca production index} = -0.461 \text{ MaxRatio} + 0.257 \text{ MaxTemp} - 0.211 \text{ MinTemp} \tag{14}$$

*Food production index* = −0.190 *MaxRain* + 0.268 *MaxTemp* + 0.484 *MinTemp* (15)
