1 2 {{alias}}( x, μ, s ) 3 Evaluates the logarithm of the cumulative distribution function (CDF) for a 4 logistic distribution with location parameter `μ` and scale parameter `s` at 5 a value `x`. 6 7 If provided `NaN` as any argument, the function returns `NaN`. 8 9 If provided `s < 0`, the function returns `NaN`. 10 11 Parameters 12 ---------- 13 x: number 14 Input value. 15 16 μ: number 17 Location parameter. 18 19 s: number 20 Scale parameter. 21 22 Returns 23 ------- 24 out: number 25 Evaluated logCDF. 26 27 Examples 28 -------- 29 > var y = {{alias}}( 2.0, 0.0, 1.0 ) 30 ~-0.127 31 > y = {{alias}}( 5.0, 10.0, 3.0 ) 32 ~-1.84 33 > y = {{alias}}( 2.0, 0.0, NaN ) 34 NaN 35 > y = {{alias}}( 2, NaN, 1.0 ) 36 NaN 37 > y = {{alias}}( NaN, 0.0, 1.0 ) 38 NaN 39 40 41 {{alias}}.factory( μ, s ) 42 Returns a function for evaluating the logarithm of the cumulative 43 distribution function (CDF) of a Logistic distribution with location 44 parameter `μ` and scale parameter `s`. 45 46 Parameters 47 ---------- 48 μ: number 49 Location parameter. 50 51 s: number 52 Scale parameter. 53 54 Returns 55 ------- 56 logcdf: Function 57 Logarithm of cumulative distribution function (CDF). 58 59 Examples 60 -------- 61 > var mylogcdf = {{alias}}.factory( 3.0, 1.5 ); 62 > var y = mylogcdf( 1.0 ) 63 ~-1.567 64 65 See Also 66 -------- 67
