How To Read Autocorrelation Table
The periodic table of elements contains the building blocks that make up the objects in our world. Water is a combination of hydrogen and oxygen atoms. Carbon atoms are in all living things. As of 2016, the periodic table contains 118 unique elements. You will see two items in the results window. The first is the autocorrelation matrix. The second is the correlations under the stationarity assumption, where the row number corresponds to the time lag. In the graph window, two plots will come up at the end.
HelloI'm running a panel data regression, with 5 independent variables and 28 firms over 5 years. I have 140 observations.After running a Hausman test, i found that a FE reg is to be used. Next I tested for heteroscedasticity - using the Cook-Weisberg httest for residuals - and autocorrelation - using the xtserial command for panel data.
Both turned positive. My data is characterized by both heteroscedasticity and autocorrelation.I then looked for ways to correct for them. I learned the following: heteroscedasticity - use robust (eg. Xtreg dep, var1, var2., fe vce(robust)) autocorrelation - use Cochranne Orcutt method (prais dep, var1, var2., corc)But I need to correct them simultaneously in a single regression. I did found something using google:the Newey-west method.I ran newey dep, var1, var2., lag (1) forceMy questions and problems are as follows: How to obtain r-squared when running newey? is there another more efficient way of correcting for both autocorrelation and heteroscedasticity?
should i run dfuller to ensure stationarity? Preemptive priority scheduling program in cpp. If yes, how to interpret dfuller please?Any help would be much appreciated. Dear all,I have more or less the same question.
I read the article suggested in this post but I'm a bit confused which analysis to use in STATA to generate the right results. The analysis of my unbalanced panel dataset implies that the FE model has to be used, next to this both heteroskedasticity and autocorrelation are present. I did a lot of research on the internet and articles and different options show up on how to deal with this, I'm not sure which model is the most valid for this particular case. The options that I found and are also present in the suggested article are:xtreg, fe robust - however, my results turn up to be non-significant when using this analysisxtreg, fe vce(robust) - however, this option does not control for autocorrelation according to the article of Hoechle.xtscc, feAs far as I understand the xtscc, fe option turns out to be the best option. However, I'm not sure if the sample is cross-sectionally dependent.
Can someone please explain me the differences between those options and which one turns out to be the best option in my case? Thank you in advance!Kind regards,Jeroen.
