1 2 {{alias}}( p, v ) 3 Evaluates the quantile function for a Student's t distribution with degrees 4 of freedom `v` at a probability `p`. 5 6 If `p < 0` or `p > 1`, the function returns `NaN`. 7 8 If provided `NaN` as any argument, the function returns `NaN`. 9 10 If provided a non-positive value for `v`, the function returns `NaN`. 11 12 Parameters 13 ---------- 14 p: number 15 Input probability. 16 17 v: number 18 Degrees of freedom. 19 20 Returns 21 ------- 22 out: number 23 Evaluated quantile function. 24 25 Examples 26 -------- 27 > var y = {{alias}}( 0.8, 1.0 ) 28 ~1.376 29 > y = {{alias}}( 0.1, 1.0 ) 30 ~-3.078 31 > y = {{alias}}( 0.5, 0.1 ) 32 0.0 33 34 > y = {{alias}}( -0.2, 0.1 ) 35 NaN 36 37 > y = {{alias}}( NaN, 1.0 ) 38 NaN 39 > y = {{alias}}( 0.0, NaN ) 40 NaN 41 42 > y = {{alias}}( 0.5, -1.0 ) 43 NaN 44 45 46 {{alias}}.factory( v ) 47 Returns a function for evaluating the quantile function of a Student's t 48 distribution with degrees of freedom `v`. 49 50 Parameters 51 ---------- 52 v: number 53 Degrees of freedom. 54 55 Returns 56 ------- 57 quantile: Function 58 Quantile function. 59 60 Examples 61 -------- 62 > var myQuantile = {{alias}}.factory( 4.0 ); 63 > var y = myQuantile( 0.2 ) 64 ~-0.941 65 > y = myQuantile( 0.9 ) 66 ~1.533 67 68 See Also 69 -------- 70
