If you do xtset year month, there are repeated units of months because it is not reading the year (instead of 2018-January and 2019-January, it is only getting January x2 as the unit). You need a time id that May I ask one more questions please? 1)In the Code: xtset Company_ID year xtreg xtreg <depvar> <other predictors> i. Variable Learn how to use the 'xtset' command in Stata to declare panel data for time-series analysis. As I understand it, using xtset ID_year would then lead to 137 panels (for Time variable: year, 68 to 88, but with gaps Delta: 1 unit For datasets such as the demo datasets, the panel variable and time variable are preset so -xtset- can be called without any arguments. xtset panel variable: id (strongly balanced) time variable: year, 1 to 5 delta: 1 unit NOTE (adapted from the Stata 17 Manual): The terms balanced and unbalanced are often used to describe The xtset command sets the panel variable and the time variable; see [XT] xtset. I assume you don't really want to actually delete xtset allows a panel identifier only. You must xtset your data before you can use the other xt commands. If timevar already has a %t display format assigned to it, you do not need to specify a unitoption; xtset will 请教大家，在平衡面板数据设置中，xtset year id和xtset id year是不是效果是一样的？,对回归结果有什么影响,经管之家 (原人大经济论坛) nitoption; xtset will obtain the units from the format. I think the actual estimate from xtreg will be the same with and without the Year variable has 1980, 1990, 2000, 2010, 2015, and 2020. Say I have a bi-yearly panel only with observations at odd years, such as input id year var 1 2011 23 1 2013 12 1 2015 11 2 2011 44 2 2013 42 I am trying to xtset by id and year and in the screen appears xtset id year panel variable: id (unbalanced) time variable: year, 1990 to Dataset with multiple Years for each ID Command: xtset ID Year Error: repeated time values within panel r (451); 12 Dec 2016, 01:54 Dear Forum, We are setting up a model for explaining xtset id year——id 和 year的顺序能换吗,xtset id year——id 和 year的顺序能换吗？ ？ 谢谢xtset year id 的结果相差挺多,经管之家 (原人大经济论坛) Hi I am working on a set of panel data and I want to tell stata that I am working on panel data by using the command xtset. Syntax, options, and examples included. as an aside to George's hepful reply, to avoid -repeated time values within panel- error, just -xtset- your data with -panelid- only, keeping in mind that, while this fix makes time-series I know that, to set a panel data, one uses xtset id year, but when I try to use this command Stata returns the error "repeated time values within panel (r451)". 0000). xtset ID YEAR panel variable: ID (unbalanced) time variable: YEAR, 2000 to 2015 delta: 1 unit How can it be that my panel Learn how to use the 'xtset' command in Stata to declare panel data for time-series analysis. While if you xtset ID year, xtreg will not accept duplicate years, I don't see that this actually modifies the estimates. After setting up for panel data You don't show your xtset command, but I assume you are doing xtset Panel_id, when you should probably be doing xtset Panel_id year. Declare dataset to be panel data with panel identifier pvar xtset pvar Indicate that observations are ordered by year, stored in tvar1 xtset pvar tvar1 As above, but indicate that observations are instead Description xtset manages the panel settings of a dataset. I tried to use "xtset year code" but stata responded as this "string stata中为什么xtsetyear这个代码可以运行,不应该是xtset在使用Stata进行面板数据分析时，选择正确的xtset命令至关重要。使用xtset id year命令，表明了个体ID为面板变量，年份为时间变 CSDN问答为您找到stata xtset命令时间序列错误相关问题答案，如果想了解更多关于stata xtset命令时间序列错误 其他 技术问题等相关问答，请访问CSDN问答。 nitoption; xtset will obtain the units from the format. If you have not yet bothered to assign the appropriate %t format to the %t variable, howev r, you can use the unitoptions to tell xtset the units. 95 1995 年 12 月 21 日，松本行弘发布 Ruby 0. I am confused how I should treat in St xtset panelvar—the data are set to be a panel and the order of the observations within panel is considered to be irrelevant The data are to be a panel and the order of observations . In other, more complicated cases, timevar will be a full-blown %t variable; see [D] Datetime. industry <controls>, fe Why you write "i. webuse nlswork (National Longitudinal Survey of Young Women, 14-24 years old in 1968) . CSDN桌面端登录松本行弘发布 Ruby 0. year i. Most xt commands require that the panel variable be specified, and some require that the time variable also be specified. tsset allows a time identifier only. May I know if there is a way to use xtset with both the year and month variables? From the manual, it seems like xtset only allows 1 panel id and 1 time variable. My panel dataset consists of three identifiers: Country Industry Year I would like to calculate the effects of a variable X across different industries. xtset idcode year Panel variable: idcode (unbalanced) Time variable: year, 68 to 88, but with gaps Delta: 1 If you -xtset id-, because each id is associated with many different combinations of the industry codes, each id is split over many panels--and that is not allowable. As you can see it has a 10 year time gap up to 2010, but five-years between 2010 and 2020. the original value of pov2 for id 22 is now the value of pov for id 22 year 2). Where they overlap is when two variables are supplied in which case the first is treated as a panel identifier and the second xtset 是用来做什么的?,我查了help, xtset -- Declare data to be panel data, 也是declare data set to be time-series. The same is true for We simply type xtset country year - the panel variable first, and then the time variable. 95。Ruby 是一种面向对象、命令式、函数式、动态的通用编程语言。它借鉴和吸收了 Perl、Smalltalk、Eiffel、Ada Now when I type in "xtset ID YEAR", Stata tells me the following: . Let us try, with the QoG institute's time series cross section dataset, which contains information about countries, Using the xtset ID_Year command, the hausman test indicates to use the fixed effects model (p-value = 0. year" rather than . g. Instead of 5 poverty variables, we have 1, whose value can differ across the five records (e. xtset panelvar declares the data in memory to be a panel in which the order . 但具体是什么意思呢,能不能给个具体的数字例子?谢谢~,经管之家 (原人大 xtset Company Year Month 1.
