- NAME
- ols - Estimate linear regressions.
-
- SYNOPSIS
- ols [-_✓h] [-_✓p] [-_✓r_✓a_✓w] [-_✓l labelstring] [-_✓m model_spec ]
- [-_✓e_✓p_✓p] [_✓i_✓n_✓p_✓u_✓t_✓f_✓i_✓l_✓e_✓n_✓a_✓m_✓e]
-
- DESCRIPTION
- _✓o_✓l_✓s takes a set of observations from the specified input
- file. There must be exactly one observation per line. If no
- input file is specified, _✓o_✓l_✓s reads data from Standard Input.
-
- How is this input file organised? All lines must have the
- same layout of variables (fields), and the same number of
- variables. Given a set of variables in a data file, you can
- run any regression which uses some (but not necessarily all)
- of these variables as l.h.s. or r.h.s. variable(s).
-
- Defining the layout of the input lines and choosing r.h.s.
- and l.h.s. variables "by hand" is slightly tedious. _✓o_✓l_✓s
- offers a default behaviour which might be useful. In the
- event that you do not choose l.h.s. and r.h.s. variables
- yourself, it assumes you want a regression as follows: the
- last (rightmost) variable on each line is considered to be
- the l.h.s. variable and all other variables are used as
- r.h.s. regressors.
-
- The Intercept
- _✓o_✓l_✓s knows nothing about the intercept of the regression
- line. By default, there is no intercept. If you want an
- intercept, you must include a variable in the dataset which
- always takes the value 1.0. This is readily done using Unix
- tools like _✓a_✓w_✓k(1) or _✓s_✓e_✓d(1).
-
- Notice that omitting the intercept implies _✓f_✓o_✓r_✓c_✓i_✓n_✓g the
- regression line to pass through the origin. If this res-
- triction is forced unintentionally, it will almost certainly
- lead to nonsensical results. Make sure you have a good rea-
- son for wanting to impose such a restriction, and be aware
- that _✓o_✓l_✓s will implicitly impose this restriction if you do
- not include a r.h.s. regressor which always takes the value
- 1.
-
- OPTIONS
- -h This option gives some minimal quickstart help. All
- other arguments are ignored if it is found.
-
- -l labelstring
- This option allows you to attach variable names to your
- variables. Thus, if you have three numbers per line in
- a regression of _✓y on _✓x with an intercept, you could use
- a labelstring of the form 'constant x y'.

- The labels do several things. They help in the pretty
- printing of the regression results. When the -p switch
- is used, the labels enable a more readable generated
