Package: QForm 0.2.2

QForm: Fast, safe CDF and PDF estimation and bounding for generalized chi-square random varaibles and quadratic forms

QForm provides estimates and upper/lower bounds on p-values for test statistics of the form \deqn{\sum\limits_i f\left(\eta_i \right) A_i + \sigma Z_0}{\sum\limits_i f (\eta_i) A_i + \sigma Z_0} where each \eqn{A_i \sim \chi^2_{a_i}\left(\delta^2_i\right)}{A_i \sim \chi^2_{a_i}\left(\delta^2_i\right)} and \eqn{Z_0 \sim N(0,1)}{Z_0 \sim N(0,1)}, all terms mututally independent.
