发生这种情况的原因是因为Stata不允许在某些命令中使用optionse选项。解决方法：1. 尝试使用不同的命令，如果可以使用optionse选项，则可以解决问题。2. 尝试使用不同的参数，如果可以使用optionse选项，则可以解决问题。3. 尝试使用不同的数据集，如果可以使用optionse选项，则可以解决问题。4. 尝试使用不同...
wntestq varname [if] [in] [, lags(#)] 其中,中括号内的内容可以省略。 这意味着在使用该语句时,可以不规定滞后阶数, 此时Stata默认滞后阶数为min{floor(n/2)-2,40} (此处floor表示向下取整) 我从Excel表中将年龄数据粘贴到了stata中,不只为什么显示为红色字(即为字符型),我使用destring a103,replace...

A greater number of lagged values may be included in the test via the lags option. Stata Technical Bulletin 15 Remarks pThe Breusch–Godfrey test is a general test of the null hypothesis that the regression errors t are independently distributed, versus the alternative that their distribution ...
(numlist): set lag lengths, maxlags(numlist): set maximum lag lengths, ec: display output in error-correction form, ec1: like option ec, but level variables in t − 1 instead of t, aic: use AIC as information criterion instead of BIC, exog(varlist): exogenous variables in the ...

While you can specify eci to force presentation of the empirical confidence interval, you should not. leave, allowed only with bs, specifies that a data set of the bootstrapped statistic be left behind in place of the data currently in memory. The default is to leave the original data ...
