This post is a Mata version of Programming an estimation command in Stata: Using Stata matrix commands and functions to compute OLS objects. Downloadable! I could use the expression matrix(r(StatTotal)’) rather than creating a new matrix, but I wanted to show you the transposed matrix before writing it to Excel. Store the descriptive statistics of a variable in a macro in Stata. 0. covariance matrix estimates Christopher F Baum1 Austin Nichols2 Mark E Schaffer3 1Boston College and DIW Berlin 2Urban Institute 3Heriot–Watt University, IZA and CEPR German Stata Users Group Meeting, July 2011 Baum, Nichols, Schaffer (BC / UI / HWU) Cluster-Robust Covariance Matrices GSUG’11, July 2011 1 / 57 . But what I'm trying to get at is how to store the e(b) (i.e. st: Cannot initialize matrix to store summed coefficient estimates. Stata/IC network 2-year maintenance Quantity: 196 Users Qty: 1. The procedure for using estout is to ﬁrst store several models using the estimates store command and then apply estout to save or display a table of the estimates. o eststo may be used as a prefix command (see help prefix). Producing a fully formatted end-product may involve specifying many options. the data set. Working with Stata regression results: Matrix/matrices, macros, oh my! You may have to merge the resulting variables back with the original dataset if you want to have them both together. mtab1 is a command of making an one-way table and store the results (frequencies and percentages) in matrix. However, consider the following Finally, the matrix v is the Kronecker product of s and i resulting in a 400 by 400 matrix. quietly regress price mpg weight . Joao, Thanks for your response; that helps a bit. 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 *. This is the fourteenth post in the series Programming an estimation command in Stata. 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. Please help. The upper-left corner of the matrix will be placed in cell A1 of the Excel table. Most Stata procedures store some, many or perhaps all elements that were used during computation in memory from which they can be retrieved; they remain available until the next procedure produces new elements to be stored. 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). 0. Want to double-check Stata’s regression estimates? 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). dm0037c 2008 StataCorp LP.
