Nettet5. jul. 2024 · The following graph shows a scatter plot of the newly transformed data along with histograms for each marginal distribution. The histograms show that the columns X1 and X2 are distributed as gamma and lognormal, respectively. The joint distribution is correlated. What about the Pearson correlation? Nettet12. apr. 2024 · Q2. Are marginal and conditional distributions always the same? A2. No, they are not always the same. In fact, in many cases, they can be very different. For instance, consider the joint distribution of two variables X and Y. If X and Y are independent, then the marginal distribution of X and the conditional distribution of X …
