... If a variable is statistically insignificant at the usual levels (10%, 5%, 1%), one may think of dropping it from the regression. If the sample size is small, effects might be imprecisely estimated so that the case for dropping insignificant variables is less strong. If on the basis of a test ...

COPPER CONCENTRATE CRM, OREAS 99 Summary Statistics
... The meaning of these tolerance limits may be illustrated for copper, where 99% of the time at least 95% of subsamples will have concentrations lying between 25.85 and 25.93 %. Put more precisely, this means that if the same number of subsamples were taken and analysed in the same manner repeatedly, ...
