Data File with Soft Data Use five data columns Data Type Value1 Value3 Data - Value2

- Value4 Type field Specify data types (Hard/Uniform/Gaussian/ Triangular /Truncated Gaussian) Value1, fields

Value2, Value3, and Value4 Data Types Hard Data Data Type: 0 Value1&2 Fields: Data Value Soft Data (Uniform) Data Type: 1 Value1 Field: Lower Bound Value2 Field: Upper Bound Value3 & 4 Field: Dummy

Soft Data (Gaussian) Data Type: 2 Value1 Field: Mean Value2 Field: Standard Deviation Value3 & 4 Fields: Dummy Data Types Soft Data (Triangular) Data Type: 1 Value1 Field: Lower Bound Value2 Field: Upper Bound

Value3 Field: Mode Value4 Field: Dummy Soft Data (Trunc. Gaussian) Data Type: 4 Value1 Field: Mean Value2 Field: Standard Deviation Value3 Field: Lower Trunc.Value Value4 Field: Upper Trunc. value Data File Example Lower Bound: 24.5

Data Type: 1 (Uniform) Upper Bound: 51.45 Mean: 18.1 Data Type: 2 (Gaussian) Standard Dev: 38.01 Data File Example Use Data Type

To use soft data, check Use DataType Set Data Type, Value1 Field, and Value2 Field Hardened Data Histogram/Basic statistics Soft data is

hardened Uniform Mid-point Gaussian Mean value Std. formulas for others Hardened are used in values

Histogram Explanatory data analysis Mean trend estimation Exploratory Data Analysis Hardened data is used Temporal Evolution tab Hard data: Blue circle Soft data: red triangle
