set memory [n] [k|m|g] •n表示设置的内存大小,可以是一个正整数。 •k表示设置大小单位为千字节(KB)。 •m表示设置大小单位为兆字节(MB)。 •g表示设置大小单位为千兆字节(GB)。 使用示例 示例 set memory 50m 上述命令将内存大小设置为50MB。 示例 set memory 1g 上述命令将内存大小设置为1GB。 示例
memory displays a report on Stata's current memory usage. query memory displays the current values of Stata's memory settings. set maxvar, set niceness, set min memory, set max memory, and set segmentsize change the values of the memory settings. If you are a Unix user, see Serious bug...
Virtual memory is slow but adequate in cases when you have a dataset that is too large to load into real memory.If you wish to limit the maximum amount of memory Stata can use,you can set max memory;see[D]memory.If you use the Linux operating system,we strongly suggest you set max ...
However, under some Irix environments, Stata may not allocate large amounts even when sufficient memory is available. A typical error message would look like the following: . set mem 8000m op. sys. refuses to provide memory r(909);

在消费行为研究中同时使用系统聚类与K均值方法会产生互补效果。系统聚类适合探索性分析，通过树状图判断合适分类数；K均值则适用于验证性分析，快速处理大规模数据。建议每次执行聚类命令前使用setseed命令固定随机种子，确保结果可复现。遇到样本缺失值时，需先行处理缺失数据，否则会触发Stata的错误提示中断分析进程。
