Title
  • DATMAT: Stata module to multiply variables via matrix multiplication
Author
  • Bill Sribney
Physical Description
  • code
Notes
  • Consider the k variables in "oldvarlist" as an N x k matrix, where N is the number of observations. The matrix called "matname" is a k x m matrix. Then the resulting matrix product of "oldvarlist"*"matname" is a N x m matrix, whose m columns become m new variables in "newvarlist". Windows users should not attempt to download these files with a web browser. Note that the matrix multiplication performed by -datmat- is purely positional; i.e., it does just what you expect based on the order of the variables, observations, and rows and columns of "matname". Windows users should not attempt to download these files with a web browser. The row and column names of the matrix "matname" are ignored. This is different from the behavior of matrix score.
