Generates a new column with values selected from the selected
distribution. There are two numerical parameters which can be
controlled, Value1 and Value2. Based on the distribution which is
selected the parameters have different meanings. See the section below
for an explanation.
Gaussian
- Value1: mean
- Value2: standard deviation > 0
Exponential
- Value1: mean > 0
- Value2: not used
Gamma
- Value1: shape > 0
- Value2: scale > 0
T
- Value1: df the degrees of freedom > 0
- Value2: not used
Weibull
- Value1: shape > 0
- Value2: scale > 0
Beta
- Value1: alpha
- Value2: beta
Cauchy
- Value1: median
- Value2: scale
ChiSquare
- Value1: df - the degrees of freedom
- Value2: not used
F
- Value1: numeratorDf - the numerator degrees of freedom > 0
- Value2: denominatorDf - the denominator degrees of freedom > 0
Uniform
- Value1: lower > upper
- Value2: upper
The generation is performed with the Data Generators as provided by Apache Commons Math.
