Webrayleigh is a special case of chi with df=2. The probability density above is defined in the “standardized” form. To shift and/or scale the distribution use the loc and scale parameters. Specifically, rayleigh.pdf (x, loc, scale) is identically equivalent to rayleigh.pdf (y) / scale with y = (x - loc) / scale. Note that shifting the ... WebPutnam-Norden-Rayleigh Curve. In the study of software project scheduling, the Putnam-Norden-Rayleigh Curve, also known as the PNR Curve, is a graphical curve derived from a mathematical equation that indicated the relationship between applied effort and delivery time in relation to a software project.A PNR curve can be used to determine the least cost …
