Data descriptor: Daily observations of stable isotope ratios of rainfall in the tropics. We explore the relationships and generate generalized linear regression models between temperature, humidity, sunshine, pressure, and evaporation. After generating the tree with an optimal feature set that maximized adjusted-R2, we pruned it down to the depth of 4. Benedetti-Cecchi, L. Complex networks of marine heatwaves reveal abrupt transitions in the global ocean. The R-squared is 0.66, which means that 66% of the variance in our dependent variable can be explained by the set of predictors in the model; at the same time, the adjusted R-squared is not far from that number, meaning that the original R-squared has not been artificially increased by adding variables to the model. In the first step, we need to plot visualization between ARIMA Model, ETS Model, and our actual 2018 data. Logs. Rainfall forecast, including whether or not it will rain tomorrow at a specific hour.
