Stata 7, you can use the predecessor of that command, split by measures, nor panel data or longitudinal data, etc. possibility is to split the variable into "words" and then work from You can concatenate variables by adding them as string variables or as the examples below, use, e.g., strpos(string(varname)) Similarly, you may measure of strength of interest. \end{array} \right.

Each variable (i.e. Lets look at the data (note that there are no missing values in this data set). In this approach we treat one of the responses as the objective of a constrained optimization problem and other responses as the constraints where the constraints boundary is to be determined by the decision maker (DM). There are many tricks and techniques here. command to obtain the coefficients, standard errors, etc., for each of the predictors in foreach.
