WebIn R, a family specifies the variance and link functions which are used in the model fit. As an example the “poisson” family uses the “log” link function and “ μ μ ” as the variance function. A GLM model is defined by both the formula and the family. GLM models can also be used to fit data in which the variance is proportional to ...

WebOct 26, 2024 · The Pearson correlation coefficient, sometimes known as Pearson’s r, is a statistic that determines how closely two variables are related. Its value ranges from -1 to +1, with 0 denoting no linear correlation, -1 denoting a perfect negative linear correlation, and +1 denoting a perfect positive linear correlation. WebPearson Correlation Formula. The name correlation suggests the relationship between two variables as their Co-relation. The correlation coefficient is the measurement of correlation. To see how the two sets of data are connected, we make use of this formula. The linear dependency between the data set is done by the Pearson Correlation coefficient.
