normalPDF — Defines a normal (Gaussian) probability density function
In a normally distributed random variable, a symmetrical distribution of given standard deviation is assumed about the nominal value (which is given elsewhere in the parent element). The correlatesWith sub-element references other functions or variables that have a linear correlation to the current parameter or function. The correlation sub-element specifies the correlation coefficient and references the other function or variable whose random value helps determine the value of this parameter.
