Closed suhchc closed 1 year ago

suhchc commented 2 years ago

Hello, while trying to use estat imapct after successfully run nwxtregress, Stata gives the following error message, wondering if it is a bug.

. estat impact ----+--- 10 --+--- 20 --+--- 30 --+--- 40 --+--- 50 % J(): 3900 unable to allocate real [2147379216,50] SparseMultiply(): - function returned error BarryPace(): - function returned error calc_DIEffects(): - function returned error

: - function returned error r(3900); Stata 16.1

Hi, I think the problem might be the dimensions of your data and that mata cannot create a large enough matrix. How many cross-sectional units and time periods do you have?

Hello Dr. Ditzen,

The relationship data is a cross sectional dataset with 3656 relationship pairs, one time period. I attached the relationship dataset if it helps. The cross-sectional number of units in the main analysis is 5298, also one time period. Thank you.
