If X and Y are independent, Pearson’s correlation coefficient is

If X and Y are independent, Pearson’s correlation coefficient is 0. A positive r value for the correlation implies a positive association (large Compound Library solubility dmso values of X tend to be associated with large values of Y, and small values of X tend to be associated with small values of Y). A negative value for the correlation means an inverse association (large values of X tend to be associated with small values of Y, and vice versa).

In the analysis of the relationship between the low and high-titre infections, is the average R value Inhibitor Library ic50 of the low-titre infection at a given time point, and is the average R value at the same time point in the high-titre infection. SX and SY are the SEM (standard error of the mean) values and n is the sample number.
