AsymptoticProbability

AsymptoticProbability[pred,xdist,aa0]

computes an asymptotic approximation for the probability of pred centered at a0, under the assumption that x follows the probability distribution dist.

AsymptoticProbability[pred,{x1,x2,…}dist,aa0]

computes an asymptotic approximation for the probability of pred centered at a0, under the assumption that {x1,x2,…} follows the multivariate distribution dist.

AsymptoticProbability[pred,vars,{a,a0,n}]

computes the asymptotic probability to order n.

Details and Options

  • Asymptotic approximations for probabilities are used to study the limiting behavior of probability distributions in statistics. Examples of such uses include the central limit theorem and the approximation of the binomial distribution by a normal distribution.
  • AsymptoticProbability[pred,vars,aa0] computes the leading term in an asymptotic expansion for the probability of pred. Use SeriesTermGoal to specify more terms.
  • The center a0 can be any finite or infinite real or complex number.
  • The order n must be a positive integer and specifies the order of approximation for the asymptotic solution. It is not related to polynomial degree.
  • The following options can be given:
  • Assumptions$Assumptionsassumptions to make about parameters
    GenerateConditionsAutomaticwhether to generate answers that involve conditions on parameters
    MethodAutomaticmethod to use
    PerformanceGoal$PerformanceGoalaspects of performance to optimize
