Initial assignment to linkage groups was based on the logarithm of the odds ratio for each possible marker pair.
proportional to the logarithm to the base 10 of the concentration
The coefficients of this regression are the logarithm of the odds ratio.
The relationship between water potential and vapor pressure is well defined also, being proportional to the logarithm of the ratio of actual vapor pressure to the saturation vapor pressure.
It was a 17th century Scottish baron, John Napier, who first discovered the power of the logarithm as an important function in mathematics.
The logarithm remains an important mathematical function but its use in calculating has gone for ever.
All reading times were converted to words read per minute, then transformed to base 10 logarithms for the analyses because they were positively skewed.
He observed that the pages of heavily used books of logarithms were grimier at the beginning than at the end, suggesting that fellow scientists tended to look up smaller numbers more often than larger ones.
The computation of logarithms had made him aware of the inaccuracy of human calculation around 1812.
They sketch a normalization algorithm, which is based on computing logarithms of transition matrices which they approximate by power series.
