Given a dataset of 10,000 observations with 15 predictor variables and a continuous response variable, use a non-parametric regression approach (e.g., random forests, gradient boosting) to identify the most influential predictors and estimate the relationship between the predictors and the response variable. Perform a 5-fold cross-validation to evaluate the model's performance and provide a detailed report on the results, including plots of the predicted vs. actual values and a discussion of the implications for future research.

Develop a statistical framework for detecting anomalies in a time series dataset of daily sales figures for a retail company, using a combination of techniques such as exponential smoothing, seasonal decomposition, and machine learning-based approaches (e.g., one-class SVM, local outlier factor). Evaluate the performance of each method using metrics such as precision, recall, and F1 score, and provide a recommendation for the most effective approach based on the results.

Given a weighted graph representing a transportation network with 50 nodes and 100 edges, use a combination of graph theory and optimization techniques (e.g., minimum spanning tree, shortest path algorithms) to identify the optimal subset of edges to upgrade or reinforce in order to minimize the overall network cost while maintaining a minimum level of connectivity and redundancy. Provide a detailed report on the optimized network topology, including visualizations of the original and optimized networks.

Develop a framework for performing sensitivity analysis on a complex system modeled by a set of ordinary differential equations (ODEs), using techniques such as Morris screening and Sobol indices to quantify the uncertainty in the model outputs and identify the most influential parameters. Apply this framework to a case study of a population dynamics model, and provide a detailed report on the results, including plots of the sensitivity indices and a discussion of the implications for model calibration and validation.
