Sensitivity analysis toolbox

The sensitivity analysis toolbox is a plugin to Ecolego which extends the basic sensitivity analysis tools in Ecolego.

Methods

• Pearson - Pearson product-moment correlation coefficient ^*
• Spearman - Spearman’s rank correlation coefficient ^*
• SRC - Standardized Regression Coefficient ^*
• SRRC - Standardized Rank Regression Coefficient ^*
• PCC - Partial Correlation Coefficient ^*
• PRCC - Partial Rank Correlation Coefficient ^*
• Morris - A computationally inexpensive global screening method
• Garten - OAT design to compute customized impact of input factors on model output
• Local - OAT design to compute local impact of input factors on model output
• Variance-based methods:

Charts

Two new charts are included with the toolbox.

• Correlation time chart - A chart which plots correlation coefficients over time.

• Correlation pie chart - A pie chart with correlation coefficients.
