Theorem: Let X X be a random variable following a normal distribution: X ∼ N (μ,σ2). (1) (1) X ∼ N ( μ, σ 2). erf (x) = 2 √π ∫ x 0 exp(−t2)dt. (3) (3) e r f ( x) = 2 π ∫ 0 x exp ( − t 2) d t. Proof: The probability density function of the normal distribution is:
Web23 de nov. de 2010 · The CDF has a simple non-parametric estimator that needs no choices to be made: the empirical distribution function. It's not quite so simple to estimate a PDF. If you use a histogram you need to choose the bin width and the starting point for the first bin. If you use kernel density estimation you need to choose the kernel shape and bandwidth. Web7 de jan. de 2015 · $\begingroup$ @Dilip For very low precision applications, such as computer graphics, sine and cosine can indeed be optimized by use of suitable lookup tables. For statistical applications, though, such optimization is never used. Ultimately it's not really any harder to compute $\text{erf}^{-1}$ than $\log$ or $\text{sqrt}$, but on modern …
