1 2 {{alias}}( [N, K, n] ) 3 Returns a hypergeometric distribution object. 4 5 Parameters 6 ---------- 7 N: integer (optional) 8 Population size. Must be a nonnegative integer larger than or equal to 9 `K` and `n`. 10 11 K: integer (optional) 12 Subpopulation size. Must be a nonnegative integer smaller than or equal 13 to `N`. 14 15 n: integer (optional) 16 Number of draws. Must be a nonnegative integer smaller than or equal to 17 `N`. 18 19 Returns 20 ------- 21 hypergeometric: Object 22 Distribution instance. 23 24 hypergeometric.N: number 25 Population size. If set, the value must be a nonnegative integer larger 26 than or equal to `K` and `n`. 27 28 hypergeometric.K: number 29 Subpopulation size. If set, the value must be a nonnegative integer 30 smaller than or equal to `N`. 31 32 hypergeometric.n: number 33 Number of draws. If set, the value must be a nonnegative integer 34 smaller than or equal to `N`. 35 36 hypergeometric.kurtosis: number 37 Read-only property which returns the excess kurtosis. 38 39 hypergeometric.mean: number 40 Read-only property which returns the expected value. 41 42 hypergeometric.mode: number 43 Read-only property which returns the mode. 44 45 hypergeometric.skewness: number 46 Read-only property which returns the skewness. 47 48 hypergeometric.stdev: number 49 Read-only property which returns the standard deviation. 50 51 hypergeometric.variance: number 52 Read-only property which returns the variance. 53 54 hypergeometric.cdf: Function 55 Evaluates the cumulative distribution function (CDF). 56 57 hypergeometric.logpmf: Function 58 Evaluates the natural logarithm of the probability mass function (PMF). 59 60 hypergeometric.pmf: Function 61 Evaluates the probability mass function (PMF). 62 63 hypergeometric.quantile: Function 64 Evaluates the quantile function at probability `p`. 65 66 Examples 67 -------- 68 > var hypergeometric = {{alias}}( 100, 70, 20 ); 69 > hypergeometric.N 70 100.0 71 > hypergeometric.K 72 70.0 73 > hypergeometric.n 74 20.0 75 > hypergeometric.kurtosis 76 ~-0.063 77 > hypergeometric.mean 78 14.0 79 > hypergeometric.mode 80 14.0 81 > hypergeometric.skewness 82 ~-0.133 83 > hypergeometric.stdev 84 ~1.842 85 > hypergeometric.variance 86 ~3.394 87 > hypergeometric.cdf( 2.9 ) 88 ~0.0 89 > hypergeometric.logpmf( 10 ) 90 ~-3.806 91 > hypergeometric.pmf( 10 ) 92 ~0.022 93 > hypergeometric.quantile( 0.8 ) 94 16.0 95 96 See Also 97 -------- 98
