The Chi-squared statistic represents the difference between LL1, the log-likelihood of the full model and LL0, the log … Cubic regression is a process in which the third-degree equation is identified for the given set of data. A logarithmic scale (or log scale) is a way of displaying numerical data over a very wide range of values in a compact way—typically the largest numbers in the data are hundreds or even thousands of times larger than the smallest numbers.Such a scale is nonlinear: the numbers 10 and 20, and 60 and 70, are not the same distance apart on a log scale. In this page, we will discuss how to interpret a regression model when some variables in the model have been log transformed. Guidelines for interpreting correlation coefficient r .
