ols.fit | R Documentation |
This function is a switcher among various numerical fitting functions
(ols.fit.cg
, ols.fit.chol
, ols.fit.qr
,
ols.fit.svd
and ols.fit.sweep
). The argument method
does the switching: "qr"
for ols.fit.qr
, etc. This should usually
not be used directly unless by experienced users.
ols.fit(x, y, method = "qr", tol = 1e-7, maxiter = 100)
x |
design matrix of dimension |
y |
vector of observations of length |
method |

tol |
tolerance for the conjugate gradients ( |
maxiter |
The maximum number of iterations for the conjugate gradients ( |
