{{alias}}( [v] )
Returns a Student's t distribution object.
Parameters
----------
v: number (optional)
Degrees of freedom. Must be greater than `0`. Default: `1.0`.
Returns
-------
t: Object
Distribution instance.
t.v: number
Degrees of freedom. If set, the value must be greater than `0`.
t.entropy: number
Read-only property which returns the differential entropy.
t.kurtosis: number
Read-only property which returns the excess kurtosis.
t.mean: number
Read-only property which returns the expected value.
t.median: number
Read-only property which returns the median.
t.mode: number
Read-only property which returns the mode.
t.skewness: number
Read-only property which returns the skewness.
t.stdev: number
Read-only property which returns the standard deviation.
t.variance: number
Read-only property which returns the variance.
t.cdf: Function
Evaluates the cumulative distribution function (CDF).
t.logcdf: Function
Evaluates the natural logarithm of the cumulative distribution function
(CDF).
t.logpdf: Function
Evaluates the natural logarithm of the probability density function
(PDF).
t.pdf: Function
Evaluates the probability density function (PDF).
t.quantile: Function
Evaluates the quantile function at probability `p`.
