Ln(l -I- Prod) is the
natural logarithm of one plus Prod and is our innovation output measures.
In fact, the
natural logarithm of the electron-to-proton wavelength ratio is approximately 7.5 and consequently, F calibrated on the proton will be shifted by 7.5 logarithmic units relative to the F calibrated on the electron:
Scatterplots of the dependent variable LN_TBCOEF10 related to the independent variables LN_PEROOM, LN_ILLITER, and LN_INADSAN (the variables transformed to
natural logarithm now have the prefix "LN_") were then constructed.
Regression of the
natural logarithm of raw counts on time yielded a naive estimate of the intrinsic growth rate (r) of 0.084 (SE = 0.019), suggesting an average annual discrete growth rate ([lambda]) of ~1.09.
(5) When variables are expressed in
natural logarithm this was taken over the Tornqvist quantity index
Thus, our empirical specifications include the
natural logarithm of REER to capture the influence of relative prices.
It was found that only their respective
natural logarithms underwent a normal behavior (P>0.40).
In all cases, the basic idea is that the
natural logarithms of variances are modeled using a linear model to account for heterogeneity of the variances (on a logarithmic scale) in terms of covariates and factor levels.
Mathematical descriptions of certain biological transformations in soil are best described by using
natural logarithms. Most calculators have the capacity to compute
natural logarithms directly.
To document growth, the data were transformed to
natural logarithms (7).
To do so, we took the
natural logarithms of all the rates available to us and then regressed the
natural logarithms of the wages, fatality rates, and injury and illness rates against the year of observation.
