7.4. LIFMOD as a Predictor <strong>of</strong> SSSCOR<br />

<strong>The</strong> second l<strong>in</strong>guistic <strong>in</strong>dex score is SSSCOR, which, the reader will recall,<br />

was achieved by means <strong>of</strong> non-l<strong>in</strong>guistic tasks, where the speaker was<br />

concentrat<strong>in</strong>g more on the task, than on his or her language use.<br />

SSSCOR = 0.225 + 0.0100 AGE<br />

S = 0.2539 R-Sq = 43.4% R-Sq(adj) = 42.5%<br />

<strong>The</strong> p-value is highly significant, and the r-squared value is reasonable. AGE<br />

is aga<strong>in</strong> a reliable predictor <strong>of</strong> dialect ma<strong>in</strong>tenance. Next we add the variable<br />

SEX.<br />

<strong>The</strong> p-value for SEX is significant at the 0.05 level, and the r-squared value<br />

has risen slightly. Aga<strong>in</strong>, SEX is a reasonable predictor <strong>of</strong> dialect<br />

ma<strong>in</strong>tenance. Next we add the variable AGE x SEX:<br />
