1. Its the likelihood of a domino effect occurring within a tranche of a CDO. If all the companies in a CDO are in the automobile industry, and one begins to fail and therefore is unable pay its debts, there is a good chance that it might be something in the automobile industry that is causing these companies to falter. Therefore if on company fails, the probability of others failing increases.
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
Evidence that there is no correlation.
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
Yes it can be a correlation coefficient.
No, it cannot be a correlation coefficient.
Ioulia Tretiakova has written: 'The stochastic nature of default correlation'
Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
positive correlation-negative correlation and no correlation
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).

No.
Indentation rhymes with correlation
Evidence that there is no correlation.
No, The correlation can not be over 1. An example of a strong correlation would be .99
No. The units of the two variables in a correlation will not change the value of the correlation coefficient.
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
