person's income value by the logarithm function. Guidance for how data should be transformed, or whether a transformation should be applied at all, should...

In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which...

The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately...

In mathematics, a complex logarithm is a generalization of the natural logarithm to nonzero complex numbers. The term refers to one of the following, which...

this, the logit is also called the log-odds since it is equal to the logarithm of the odds p 1 − p {\displaystyle {\frac {p}{1-p}}} where p is a probability...

represents a special case of this for the normal distribution. The logarithm transformation may help to overcome cases where the Kolmogorov test data does...

In geometry and complex analysis, a Möbius transformation of the complex plane is a rational function of the form f ( z ) = a z + b c z + d {\displaystyle...

In calculus, logarithmic differentiation or differentiation by taking logarithms is a method used to differentiate functions by employing the logarithmic...

In statistics, the Fisher transformation (or Fisher z-transformation) of a Pearson correlation coefficient is its inverse hyperbolic tangent (artanh)....

numbers b, in terms of exponential and logarithm function. Specifically, the fact that the natural logarithm ln(x) is the inverse of the exponential...

{\displaystyle e^{ix}=\cos x+i\sin x,} where e is the base of the natural logarithm, i is the imaginary unit, and cos and sin are the trigonometric functions...

Antonio de Sarasa in 1647, required the natural logarithm function, a new concept. Some insight into logarithms comes through hyperbolic sectors that are permuted...

H(p)=-\int _{-\infty }^{\infty }p(x)\log {\bigl (}p(x){\bigr )}\,dx} where the logarithms may be in any base that is consistent. The equality is attained for a...

from a version used elsewhere. The q-logarithm is the inverse of q-exponential and a deformation of the logarithm using the real parameter q. ln q ⁡ (...

natural logarithm function mapping the real numbers to themselves. The logarithm of a non-positive real is not a real number, so the natural logarithm function...

deviations theory, the rate function is defined as the Legendre transformation of the logarithm of the moment generating function of a random variable. An...

for the natural logarithm of x. In pure mathematics, the notation log x generally refers to the natural logarithm of x or a logarithm in general if the...

The general logarithm, to an arbitrary positive base, Euler presents as the inverse of an exponential function. Then the natural logarithm is obtained...
