Evaluate the value of $x$, such that the Standard Normal probability distribution functional takes a given value over the interval $[\mu-x, \mu+x]$, where $\mu$ is the mean of the distribution.
Calculates the standard normal probability for the half line [-`infinity',upperBound], where -`infinity' is ``minus infinity'' and upperBound is the upper bound of the half line.
Calculates the Standard Normal probability for the interval of the real line [-`infinity',upperBound], using an estimation for the cumulative normal probability distribution function.
Calculates the Standard Normal probability for the interval of the real line [lowerBound,upperBound], using an estimation for the cumulative normal probability distribution function.
Calculates the standard normal probability for the half line [lowerBound,+`infinity'], where lowerBound is the lower bound on the half line and +`infinity' is ``plus infinity''.
Calculates the standard normal probability for the interval [lowerBound,+`infinity'], using an estimation for the cumulative normal probability distribution function.
