destring: Convert string variables to numeric variables and vice versa. encode: Encode string into numeric and vice versa. encode主要用于将数据进行编码、分组,将连续性变量转换成分组变量。 它可以和另外一组命令一起记忆:encode,decode,recode和autocode()函数 。 代码语言:javascript 代码运行次数:0 运行 A...

Stata官方建议我们合理设置数据类型: Stata keeps data in memory, and you should record your data as parsimoniously (吝啬地) as possible. If you have a string variable that has maximum length 6, it would waste memory to store it as a str20. Similarly, if you have an integer variable, it ...
这次Stata并未对age变量报错,但提示 ‘option generate() required’。带参数的选项需要指定参数类型(integer,real,string,name)和默认(不强制)值。generate需要一个name,没有默认值。尝试pnupt age, gen(2)。Stata会抱怨说2不是一个变量名。 正常情况下,选项的内容将存储在与选项同名的暂元中。 检查参数 现在我...
Infloat, 24 bits are allocated fora. Thus the largest integer that can be exactly stored is 2^0 + 2^1 + ... + 2^23 = (2^24)−1 = 16,777,215. Well, actually, 2^24 = 16,777,216 is also precisely stored because it is even, but 16,777,217 cannot be precisely stored. Us...

You can work with byte, integer, long, float, double, and string variables (including BLOBs and strings up to 2 billion characters). Stata also has advanced tools for managing specialized data such as survival/duration data, time-series data, panel/longitudinal data, categorical data, multiple-...
My main argument is that user-written Stata packages are thesource of learningadvanced Stata programming. In general, any program - whether it is written by Stata staff or a Stata user - intends to solve a problem or facilitate a task. While other users can get benefit from using the progr...
