atoti.experimental.stats.t module¶
Student’s t distribution.
For more information read:
-
atoti.experimental.stats.t.cdf(point, *, degrees_of_freedom)¶ Cumulative distribution function for a Student’s t distribution.
- Parameters

- Return type
-
atoti.experimental.stats.t.pdf(point, *, degrees_of_freedom)¶ Probability density function for a Student’s t distribution.
The pdf of a Student’s t-distribution is:
\[\operatorname {pdf}(x)=\frac {\Gamma (\frac {\nu +1}{2})}{\sqrt {\nu \pi }\,\Gamma (\frac {\nu }{2})} \left(1+\frac {x^{2}}{\nu }\right)^{-\frac {\nu +1}{2}}\]where \(\nu\) is the number of degrees of freedom and \(\Gamma\) is the gamma function.

atoti.experimental.stats.t.ppf(point, *, degrees_of_freedom)¶ Percent point function for a Student’s t distribution.
Also called inverse cumulative distribution function.
