| It is all the way between ± one sigma of the asymmetric red circles wing, observationally undiscernible. |
| Third, do immigrants receive different returns to these skills than observationally similar Canadian-born workers? |
| That gave two observationally equivalent solar theories based on two quite different mechanisms. |
| Any two consecutive cards will be observationally indistinguishable in color. |
| Even so, the statistics of pulsars are likely to be observationally biased, since signals from pulsars at great distances in the Galaxy become distorted by ionized regions of interstellar space. |
| Those results are observationally equivalent to a non-linear hysteresis that appears only at low levels of combined inflation and labour productivity growth. |
