ability to apply the appropriate advanced mathematics and statistics methods to large data sets, including, but not limited to, regression models (linear, logistic, Bayesian, stepwise, etc.), decision trees, correlation analysis, random forest models, cluster analysis, k-means, sum of squares and time series analysis. This most commonly includes conducting statistical analysis to determine trends and significant data relationships by using predictive software to create regression models (linear, logistic, Bayesian, stepwise, etc.), decision trees, correlation analysis, random forest models, and time series analysis.
