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 ...

现在尝试pnupt age。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。

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...
hist headroom, freq headroom must take on integer values r(198); An alternate solution would be to create a group variable, and then use the graph command with the freq, hist, and bin() options. . egen y = group(headroom) . list y headroom in 1/10 y head~m 1. 3 2.5 2. 4...
