std::student_t_distribution
| template< class RealType = double >
class student_t_distribution; |
|
(since C++11) |
| | |
Produces random floating-point values x, distributed according to probability density function:
- P(x|n) = · · ⎛
⎜
⎝1+⎞
⎟
⎠ -
where n is known as the number of degrees of freedom. This distribution is used when estimating the mean of an unknown normally distributed value given n+1 independent measurements, each with additive errors of unknown standard deviation, as in physical measurements. Or, alternatively, when estimating the unknown mean of a normal distribution with unknown standard deviation, given n+1 samples.
