twoway (tsline x , cmissing(n)) stata命令:predict zg if e(sample), xb 这条命令什么意思呀?关键是e(sample), xb if e(sample) 加上该条件是指用上一次回归中的样本观测值进行数据处理。相当于 if e(sample)==1 的条件语句。 predict 后面加xb是预测yhat,不加也可以。 === if e(sample) 等价...
. replace myvar = myvar[_n+1] if myvar == "" would be correct syntax, not the previous command, because the empty string""is string missing. 3. Copying previous values downwards: the cascade effect Missing values may occur in blocks of two or more. Suppose you want to replace missing...
Stata统计分析常用命令汇总一winsorize极端值处理范围:一般在1和99分位做极端值处理,对于小于1的数用1的值赋值,对于大于99的数用99的值赋值。1Stata中的单变量极端值处理:stata 11.0,在命令窗口输入findit
eliminates the need for a separate procedure to restrict data to common empirical support, meets the congruence principle, is robust to measurement error, works well with multiple imputation methods for missing data, can be completely automated, and is extremely fast computationally even with very lar...

Account for missing data in your sample using multiple imputation. Choose from univariate and multivariate methods to impute missing values in continuous, censored, truncated, binary, ordinal, categorical, and count variables. Then, in a single step, estimate parameters using the imputed datasets, ...

运⾏命令nmissing不仅可以给出指定变量串中的数值型变量的缺失值的个数，还可以给出字符型变量的缺失值的个数。选项min(#)可以显⽰缺失值个数超过#的变量及其缺失值情况。命令3:mdesc 命令mdesc也是⼀个查看变量缺失情况的第三⽅命令，它的语法结构为:mdescvarlist [if] [in] [, abbreviate(#) any all...
Stata allows users to extend its functionality through external packages, and if the package is missing or incompatible, it may result in the "stata stat is unrecognized" error. Now that we have understood the potential causes of the "stata stat is unrecognized" error, let's move on to the...
