The ti(lognormal_distribution<RealType = double>) is a probability
distribution of a random variable whose logarithm is normally distributed. If
a random variable tt(X) has a normal distribution, then tt(Y = e)sups(X) has a
log-normal distribution.
It has two parameters, em(m) and em(s) representing, respectively, the mean
and standard deviation of tt(ln(X)).
Defined types:
verb(
typedef RealType result_type;
struct param_type
{
explicit param_type(RealType m = RealType(0),
RealType s = RealType(1));
RealType m() const;
RealType s() const;
};
)
Constructor and members:
itemization(
itt(lognormal_distribution<>(RealType m = 0, RealType s = 1))
constructs a log-normal distribution for a random variable whose mean
and standard deviation is, respectively, tt(m) and tt(s).
itt(lognormal_distribution<>(param_type const ¶m)) constructs a
log-normal distribution according to the values stored in the
tt(param) struct.
itt(RealType m() const)nl()
returns the distribution's tt(m) parameter;
itt(RealType stddev() const)nl()
returns the distribution's tt(s) parameter;
itt(result_type min() const)nl()
returns 0;
itt(result_type max() const)nl()
returns the maximum value of tt(result_type);
