ρp: Actual particle density (g/cm ) ρg: Gas or sample matrix density (g/cm ) r : Least-squares coefficient of determination. The closer this value is to 1.0, the better the data fit to a hyperplane representing the relationship between the response variable and a set of covariate variables. A value equal to 1.0 indicates all data fit perfectly within the hyperplane. SpletMedian values are defined as the value where half of the population resides above this point, and half resides below this point. For particle size distributions the median is called the D50 (or x50 when following certain ISO guidelines). The D50 is the size in microns that splits the distribution with half above and half below this diameter. Spletof a log-normal distribution: Dg is the median diameter, that is, the diameter for which exactly one-half of the particles are smaller and one-half are larger; and g is termed geometric standard deviation, which is a ratio of the diameter below which 84.1% of the particles lie to the median diameter. ribbon for name
