Linear interpolation uses linear polynomials to approximate a function f(x) and construct new data points within the range of a known set of data points. normplot - Normal probability plot. Sample Plot This data is a set of 500 Weibull random numbers with a shape parameter = 2, location parameter = 0, and scale parameter = 1. You can then use the value of the shape parameter producing the most nearly linear point pattern. For example if the point pattern is curved with slope increasing from left to right, a theoretical distribution that is skewed to the right, such as a lognormal distribution, should provide a better fit than the normal distribution. Much of this is self-explanatory, for example, Mean, Std Deviation, Variance, and N. You can also specify an ANNOTATE= data set in the PROC UNIVARIATE statement to enhance all the graphics displays that the procedure creates.
