Distribute Equation Log For Free

Thus, if the random variable X is log-normally distributed, then Y = ln(X) has a normal distribution. Equivalently, if Y has a normal distribution, then the exponential function of Y, X = exp(Y), has a log-normal distribution. A random variable which is log-normally distributed takes only positive real values.

The Four Basic Properties of Logs logb(xy) = logbx + logby. logb(x/y) = logbx - logby. logb(xn) = n logbx. logbx = logax / logab.

Logarithmic functions are the inverses of exponential functions, and any exponential function can be expressed in logarithmic form.

To answer the question in your title, you can't "distribute" ln into a sum, because ln is not a factor. cos, ln, and ? are functions - there is no distributive property for functions.

Lognormal distribution of a random variable If X is a random variable and Y=ln(X) is normally distributed, then X is said to be distributed lognormally. Similarly, if Y has a normal distribution, then the exponential function of Y will be having a lognormal distribution, i.e. X=exp(Y).

Properties of Logarithmic Functions. Throughout your study of algebra, you have come across many properties?such as the commutative, associative, and distributive properties. These properties help you take a complicated expression or equation and simplify it. The same is true with logarithms.

lognormal distribution is a continuous probability distribution of a random variable whose logarithm logarithm ln(ln(x)) is normally distributed.

You can distribute logs!

Division. The rule when you divide two values with the same base is to subtract the exponents. Therefore, the rule for division is to subtract the logarithms. The log of a quotient is the difference of the logs.
