邻近映射
PROXMAP 可在.NET Framework 3.0中使用。
PROXMAP 是一种降维程序，用于构建对象（案例）之间邻近性数据（如距离或其他不相似性和相似性度量）的低维空间表示。 近程表示为低维空间中点与点之间的距离，可以直接提供或通过多元数据计算得出。
与线性投影法不同， PROXMAP 在低维解决方案中最大限度地减少了近似度和距离之间的差异。 当有多个数据源时，该程序支持个体差异模型。
- 表示法
- 正斜线 (/) 表示子命令。
- 方括号（[ ]）表示可选的子命令和关键字。
- 花括号 ({ ) 指示在元素间选择}。
- 当出现子命令和/或关键字而未作（进一步）说明时，单个星号（*）有效。
- 如果省略子命令或未指定关键字，双星号 (**) 将生效。
n是一个整数，其可能的值取决于子命令或关键字。value是一个实数，其可能的值取决于子命令或关键字。srcname是源代码（矩阵）的名称，遵循系统变量名惯例。srclist是一个源名称列表。varname是一个变量的名称。varlist是一个变量名列表。
注意： 方括号 ([ ])、大括号 ( { } ) 和星号 (**, *) 不是实际语法的一部分。
