Quantile Function of the Normal DistributionW.H. Asquith
Log-normal Φ[ln(s)] (2π)− 1/2 exp(− 0.5 ln s2) x(i) exp(Φ− 1(Pi) In Table 2.5 the normal distribution function Φ(s) is defined as Φs=12π∫−∞sexp−0.5u2du. To calculate the inverse functionΦ− 1(s) the following simple approximate expression may be use...
Some quantiles of thestandard normal distribution(i.e., the normal distribution having zero mean and unit variance) are often used ascritical valuesin hypothesis testing. The quantile function of a normal distribution is equal to the inverse of the distribution function since the latter is continuou...
BLUE of the quantile-function Q(), 0<<1 of a two-parameter normal distribution is considered based on k(陇n) selected order statistics from a finite sample of size n (up to 20). Tables of optimum ranks, coefficients and relative efficiencies (RE) (compared to the uniformly minimum ...
I used the normal distribution as an example as that’s the distribution most people seem to be familiar with. However, the concept can be applied to most distributions. Point Function Apoint functionis a way to define variable quantities that depend only on position for their values (for exam...

Line y = 0.5 intersects the graph of the distribution function along the segment (3 ≤ x < 4, y = 5). Therefore, according to definition 9.1., one has to choose u0.5 = 3. Line y = 0.1 intersects the graph of the distribution function at point (1, 1/10). Hence, u0.1 = 1. ...
