{{alias}}( [x0, Ɣ] ) Returns a Cauchy distribution object. Parameters ---------- x0: number (optional) Location parameter. Default: `0.0`. Ɣ: number (optional) Scale parameter. Must be greater than `0`. Default: `1.0`. Returns ------- cauchy: Object Distribution instance. cauchy.x0: number Location parameter. cauchy.gamma: number Scale parameter. If set, the value must be greater than `0`. cauchy.entropy: number Read-only property which returns the differential entropy. cauchy.median: number Read-only property which returns the median. cauchy.mode: number Read-only property which returns the mode. cauchy.cdf: Function Evaluates the cumulative distribution function (CDF). cauchy.logcdf: Function Evaluates the natural logarithm of the cumulative distribution function (CDF). cauchy.logpdf: Function Evaluates the natural logarithm of the probability density function (PDF). cauchy.pdf: Function Evaluates the probability density function (PDF). cauchy.quantile: Function Evaluates the quantile function at probability `p`. Examples -------- > var cauchy = {{alias}}( 0.0, 1.0 ); > cauchy.x0 0.0 > cauchy.gamma 1.0 > cauchy.entropy ~2.531 > cauchy.median 0.0 > cauchy.mode 0.0 > cauchy.cdf( 0.8 ) ~0.715 > cauchy.logcdf( 1.0 ) ~-0.288 > cauchy.logpdf( 1.0 ) ~-1.838 > cauchy.pdf( 1.0 ) ~0.159 > cauchy.quantile( 0.8 ) ~1.376 See Also --------
