#ctor(
Double(), Boolean)Construct a feature data based on a specific dataframe column data
Parameters
| Name | Type | Description |
|---|---|---|
v | Double() | the raw data matrix column data |
estimateQuantile | Boolean | - |
#ctor(
IEnumerable(Of Double()), Boolean, Int32)Streaming construction from row blocks. 面向数据总点数远超 Int32 数组上限的超大数据集: 每一行 Double() 首尾相接构成完整样本, 全程内存占用恒定.
Remarks
注意: quantile/median/mode 为近似值(精度由 histogramBins 控制), size/sum/min/max/average/variance/stdErr 为精确值.
FromBlocks(
