I have to compute and compare the least squares method on a model to the least trimmed method.
The LS model results were:
Coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) -39.9197 11.8960 -3.356 0.00375 ** Air.Flow 0.7156 0.1349 5.307 5.8e-05 *** Water.Temp 1.2953 0.3680 3.520 0.00263 ** Acid.Conc. -0.1521 0.1563 -0.973 0.34405
The LTS results were:
(Intercept) Air.Flow Water.Temp Acid.Conc. -3.580556e+01 7.500000e-01 3.333333e-01 3.489094e-17
How do I interpret the results for LTS? I know
Water.Temp are significant and
ACid.conc is not. But don't know about LTS coefficients since there are no standard errors.
