How can we plot the correlation between pixels in two images, the first clear and the other containing noise, or correlation between the samples in two sound signals? Is there a tool in Matlab or a function that achieves this purpose?
This is my code, I want to have some correlation plot with subplot , is there anyone can help me? how can I show the subplot y = triu(repmat(n+1, n, n) - (1:n)') + 0.5; x = triu(repmat(1:n, n, 1)) + 0.5;
A correlation is a statistical measure of the relationship between two variables. The measure is best used in variables that demonstrate a linear relationship between each other. The fit of the data can be visually represented in a scatterplot. Using a scatterplot, we can generally assess the r...
If your data has outliers and you are certain that they can influence the result. Then using theSpearman Correlationis the wise decision. Because outliers can’t affect theSpearman Correlationas it does toPearsoncorrelation. because Spearman uses the rank of the values instead of actual values. I...

I need to calculate the cross-correlation without losing or adding data, even though they have different sizes. The file with MPEG frames has 89000 frames and H.263 has 17000 frames. Any suggestions on how to do this in python or matlab?
一般来说,当我们谈到两个变量之间的「相关性(correlation)」时,在某种意义上,我们是指它们的「关系(relatedness)」。 相关变量是包含彼此信息的变量。两个变量的相关性越强,其中一个变量告诉我们的关于另一个变量的信息就越多。 你可能之前就看过:正相关、零相关、负相关 ...
Similar to the above example, it graphically represents using a line chart under chart options I have two variables, X & Y, where one plot on the X-axis, the other one on the Y-axis You can see the negative correlation, i.e., Variables X & Y values are negatively correlated (Negativ...
There are some key points to consider when utilizing a scatter plot to visualize your metrics. Remember correlation is not always causation. Just because the plots on your graph may show a general trend, doesn’t mean you are interpreting the data correctly. Scatter plots are excellent at ...
A correlation coefficient is a statistical value, also known as Pearson’s Correlation Coefficient (or Pearson’s r), and is always between -1 and 1. Note: outliers can make coefficients look statistically significant but not meaningful or insightful. Data points are plotted on a scatterplot and...
