Key word Category Description Example Since
if 3-args Function If function ( if(con, if_true, if_false) ) if(a=1, 2, 0) 1.0
chi 3-args Function Characteristic function for x in (a,b) - chi(x, a, b) chi(x, a, b) 1.0
CHi 3-args Function Characteristic function for x in [a,b] - CHi(x, a, b) CHi(x, a, b) 1.0
Chi 3-args Function Characteristic function for x in [a,b) - Chi(x, a, b) Chi(x, a, b) 1.0
cHi 3-args Function Characteristic function for x in (a,b] - cHi(x, a, b) cHi(x, a, b) 1.0
pUni 3-args Function Probability distribution function - Uniform continuous distribution U(a,b), usage example: 2 * pUni(x, 2, 10) pUni(x, a, b) 3.0
cUni 3-args Function Cumulative distribution function - Uniform continuous distribution U(a,b), usage example: 2 * cUni(x, 2, 10) cUni(x, a, b) 3.0
qUni 3-args Function Quantile function (inverse cumulative distribution function) - Uniform continuous distribution U(a,b), usage example: 2 * qUni(q, 2, 10) qUni(q, a, b) 3.0
pNor 3-args Function Probability distribution function - Normal distribution N(m,s) m - mean, s - stddev, usage example: 2 * pNor(x, 1, 2) pNor(x, a, b) 3.0
cNor 3-args Function Cumulative distribution function - Normal distribution N(m,s) m - mean, s - stddev, usage example: 2 * cNor(x, 1, 2) cNor(x, a, b) 3.0
qNor 3-args Function Quantile function (inverse cumulative distribution function) - Normal distribution N(m,s) m - mean, s - stddev, usage example: 2 * qNor(q, 1, 2) qNor(q, a, b) 3.0
