	Deriving Reliability Functions, this issue's Reliability Basic
		The pdf function is essentially a continuous form of a histogram, which is a bar chart that characterizes the relative frequency of an occurrence.
		This is because the area under the curve of the pdf is always equal to 1, and the cdf is essentially measuring the area under the pdf curve from zero to the point of interest.
		This function can be used to derive other functions that are important to life data analysis, including the unreliability function, the reliability function, the failure rate function, the mean life function, and the BX function.

		Calculations for the logistic distribution are presented to illustrate the case of a known but intractable cumulant generating function, and an example involving an overdispersed binomial model is presented to illustrate the case of an unavailable cumulant generating function.
		The equilibrium distribution of this chain approximates the joint distribution of the sufficient statistics associated with the parameters of interest conditional on the observed values of the sufficient statistics associated with the nuisance parameters.
		This approximation is then used iteratively in conjunction with MC methods to generate a sample from a distribution that approximates the joint distribution of the sufficient statistics associated with the parameters of interest conditional on the observed values of the sufficient statistics associated with the nuisance parameters.

		Even when a distribution may not be truly normal, it may still be convenient to assume that a normal distribution is a good approximation.
		The standard (mean=0 and variance=1) normal density function is 1 -(1/2)x^2 Z(x) = ---------- e sqrt(2pi) For mean=mu and variance=sigma^2 1 -(1/2)((x-mu)/sigma)^2 Z(x) = ---------------- e sigmasqrt(2pi) The normal distribution* with mean=mu and variance=sigma^2 is customarily referred to as N(mu,sigma^2).
		The cumulative normal, referred to here by P(X), is simply the integral of Z(x) dx from minus infinity to X. We will use Q(X) to refer to the integral of Z(x) dx from X to plus infinity.

		Defining your own functions can be handy if you need to work on a regular basis with a distribution that uses a different parameterization than the one built into the standard R function.
		The key to compounding distributions in R is that the functions that generate random deviates can all take a vector of different parameters rather than a single parameter.
		Plot the distribution and superimpose the theoretical distribution of the negative binomial with the same mean and variance to see how different the shapes of the distributions are.

	Probability density function Summary
		A probability density function is non-negative everywhere and its integral from −∞ to +∞ is equal to 1.
		Not every probability distribution has a density function: the distributions of discrete random variables do not; nor does the Cantor distribution, even though it has no discrete component, i.e., does not assign positive probability to any individual point.
		In the field of statistical physics, a non-formal reformulation of the relation above between the derivative of the cumulative distribution function and the probability density function is generally used as the definition of the probability density function.

	Cumulative Distribution Function)
		CDF, or cumulative distribution function, plots display exactly the same information as do histograms.

		CDF plots are extremely useful for quickly finding the fluorescence of a distribution corresponding to any given percentile (such as the median).
