From theCambridge English Corpus In any case, the above is a natural domain for alogarithm. From theCambridge English Corpus Figure 2 shows how taking the naturallogarithmof the values of "length of residence" transforms the curvilinear relationship into a linear one. From theCambridge English Corpus We monitored the determinant of this matrix and figure 23 shows thelogarithmof it. From theCambridge English Corpus This implies that the ratios of consumption to output and investment to output (inlogarithm) can be characterized as stationary processes. From theCambridge English Corpus Let g denote thelogarithmof a main demand aggregate that is decomposed into two subaggregates. From theCambridge English Corpus Note that as all logarithms appearing in the formulas for c1 (t) and c2 are positive, so c1 (t) and c2 are positive. From theCambridge English Corpus The independent variable for this fit was thelogarithmof the geometricmean radius in each ring (we used logarithm because the filter radius grows geometrically). From theCambridge English Corpus Initial income per capita is measured by thelogarithmof per-capita income in 1980. From theCambridge English Corpus These scores are negative logarithms of probabilities and therefore require addition as opposed to multiplication when two scores are combined. From theCambridge English Corpus Moreover, all bands predicted by the naturallogarithmrelationship have been described experimentally. From theCambridge English Corpus Because the distributions were highly skewed to the right, scores on these tasks were transformed by calculating thelogarithm. From theCambridge English Corpus Linear regressions were developed between thelogarithmof sampling-day streamflow and the chemical concentrations for each stream, ion and year. From theCambridge English Corpus On alogarithmscale, the data indicated associated transitions near 2 mm in other measured radiation and pinch parameters. From theCambridge English Corpus To ensure stationarity, we will consider the rate of growth of these variables, calculated as first differences of logarithms.
