Title

    tomata -- Make view matrices of Stata variables


Syntax

        tomata [varlist] [if] [in] [, options ]


           options      description
           -------------------------------------------------
           nomissing    casewise exclusion of missing values
           -------------------------------------------------


Description

    tomata creates separate view matrices for each variable specified or, if
    no variables are specified, all variables in the Stata dataset.


Options

    nomissing specifies that observations that contain missing in any of the
        variables are to be excluded from all view matrices created.


Remarks

    Use tomata from Stata's dot prompt, not from Mata's colon prompt.

    tomata is intended for use when you are using Mata interactively; see
    [M-5] st_view() to create view matrices within programs.

    For example, interactively, for teaching purposes, you wish to run a
    regression:

        . sysuse auto, clear

        . tomata mpg weight foreign, nomiss

        . mata:

        : y = mpg

        : X = (weight, foreign, J(rows(weight), 1, 1))

        : b = invsym(X'X)*X'y

        : b

        : end


Diagnostics

    None.
