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...

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 ...

Correlation research is a core step in understanding your data (such as from survey research) or the relationship between variables in your dataset.
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?
The correlations between the confounding variables and the exposure variable must be removed in order to isolate the causal effect. In causal inference analysis, removing the correlations between the confounding and exposure variables is called balancing, and the tool uses various balancing pr...
