But what I'm trying to get at is how to store the e(b) (i.e. mean values) into a variable [the same way as if I did egen newvar=mean(var), without acct for … ECONOMICS 351* -- Stata 10 Tutorial 3 M.G. Title stata.com estimates stats — Model-selection statistics SyntaxMenuDescriptionOption Remarks and examplesStored resultsMethods and formulasAlso see Syntax estimates stats namelist, n(#) where namelist is a name, a list of names, all, or *. Use the collapse command. Then we create another matrix i, which is an identity matrix with the number of rows and columns equal to the number of cases in the analysis, i.e., i is a 200 by 200 identity matrix. When we turn this analysis into a program, we will need to access this matrix in order to store the coefficient estimates for the bootstrap command. #delimit; clear; set mem 700m; use file1.dta; local average_income = mean income; use New.dta; gen avincome = average_income; Joao, Thanks for your response; that helps a bit. Stata's matrices, like those in any software I know, contain just one numeric element in each cell and don't allow a hierarchy of rows or columns. I have a Stata file file1.dta and one of the variables is income.I need to calculate average_income, assign it to a local macro, and store in a different Stata file, New.dta..

Store the descriptive statistics of a variable in a macro in Stata. Combining the commands can easily store the results in matrix The matrix with results can easily be further used to make tables in Excel or Word. From my understanding, it is trying to say that e(b) and e(V) are essentially matrices from users' viewpoint (behind the scenes, e() and r() matrices are not the same thing as ordinary matrices). The full syntax of estout is rather complex and is therefore to be found in the Appendix in Section 4.1 (also see estout’s online help). Official Stata estimation commands save lots of stuff, because they follow lots of rules that make postestimation easy for users. Abbott regress price weight Examine the results of this command. $11,763.00. mtab1 is a command of making an one-way table and store the results (frequencies and percentages) in matrix. Recall that b = (X'X)-1X'Y. However, note that a simple-to-use estout wrapper producing pre-formatted publication style tables is available as esttab. This question is arguably too broad and fails the criterion "Questions asking for code must demonstrate a minimal understanding of the problem being solved. sysuse auto (1978 Automobile Data) . You can do it with Stata’s matrix commands.
