====== Probabilistic SA method ====== The method estimates the following sensitivity indices: ^Sensitivity index ^When to Use ^ |Pearson product-moment correlation coefficient (Pearson)|Computes the correlation coefficient. Interesting when model is linearly depending on parameters. | |Spearman's rank correlation coefficient (Spearman) |Computes the ranked correlation coefficient. Interesting when model is linearly or monotonically depending on parameters. | |Standardized Regression Coefficient (SRC) |Sets up a regression model from the raw data. Interesting when model is linearly depending on parameters. | |Standardized Rank Regression Coefficient (SRRC) |Sets up a regression model from the ranked data. Interesting when model is linearly or monotonically depending on parameters. | |Partial Correlation Coefficient (PCC) |Computes the correlation coefficient taking into account the rest of the varying parameters. Interesting when model is linearly depending on parameters. | |Partial Rank Correlation Coefficient (PRCC) |Computes the ranked correlation coefficient taking into account the rest of the varying parameters. Interesting when model is linearly or monotonically depending on parameters.| |EASI first order correlation coefficient (EASI) |Quantifies the first order effects, if model is additive this will take into account the full variance. | ==== Settings ==== The possible settings are: ^Setting ^Explanation ^ |Iterations |The number of iterations per parameter. It equals the number of total model evaluations. | |Enable correlation |Enables correlation between input parameters. The correlation matrix is defined in the correlation matrix editor.| |Latin hypercube sampling|Uses latin hypercube sampling. If unchecked, ordinary Monte Carlo method is used. | |Seed |The seed used by methods random number generator. If it is //Auto//, a random seed will be used each time. |
