Are negative correlation and reverse correlation same?

No.

Difference between Multicollinearity and Autocorrelation?

Multicolinearity shows the relationship of two or more variables in a multi-regression model. Auto-correlation shows the corellation between values of a process at different point in times.

What is positive Correlation?

Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.

Is it possible to obtain a correlation coefficient of 1.5 for two sets of test scores?

No. Correlation coefficient is measured from +1 to -1. In addition, if the two sets of exam are exactly same, their correlation coefficient is +1.

Which one of the following correlation coefficients indicates the weakest correlation Answer - 0.01 plus 0.021 plus 0.76 - 0.88?

Assuming that all of these coefficients are based on samples of the same size then the weakest correlation is -0.01 because its absolute value (0.01) is the smallest.

What is an autocorrelator?

An autocorrelator is a device which modifies a signal with a delayed copy of itself in order to detect any periodic signal hidden in the noise.

What is the difference between Multicollinearity and Autocorrelation?

The difference between multicollinearity and auto correlation is that multicollinearity is a linear relationship between 2 or more explanatory variables in a multiple regression while while auto-correlation is a type of correlation between values of a process at different points in time, as a function of the two times or of the time difference.

Are negative correlation and reverse correlation same?

No.

What are the causes of autocorrelation?

The major causes of Autocorelation existance are 1. Mis-specification of the econometrics model (specification Error) 2. omitting an important variable 3. Natural Phenomenan 4. Lags Variables (Lags variables also create auto-correlation problem) 5. incorrect funtional relationships between variables {explained and explanatory(s)} 6. Data Manipulation

Difference between Multicollinearity and Autocorrelation?

Multicolinearity shows the relationship of two or more variables in a multi-regression model. Auto-correlation shows the corellation between values of a process at different point in times.

Is autocorrelation function a copy of original function?

No. You probably know what a sample correlation is. This statistic is often used to measure how well a linear function of one variable predicts the value of another variable. The statistic can assume any value from -1 to 1, and the extreme values show the strongest (linear) relationship. Calculating the autocorrelation function for a time series involves doing a series of calculations that are the same as those done to obtain a sample correlation coefficient. Since these values must always be between -1 and 1 they cannot in general form a copy of the original function. Here is where the idea of copying appears. Suppose you want to calculate the 1st autocorrelation coefficient from the series v0, v1, v2, v3, v4, ... . Then calculate the sample correlation for the pairs (v1, v0), (v2, v1), (v3, v2), (v4, v3), ... Notice that it is as if you were to write down the original time series on one line and then copy it on a second line shifting it one item to the right so that the pairs needed to compute the sample correlation could be read from the columns of the two lines. The 2nd autocorrelation would be computed as if by copying the second line shifting it two places to the right and so on.

What does Correlation of plus 1.00 mean?

It mean that there is no correlation between the two variables. The variables are the same.

What are the three different types of correlation?

The three different types of correlation are positive correlation (both variables move in the same direction), negative correlation (variables move in opposite directions), and no correlation (variables show no relationship).

When the variables in a correlation change simultaneously in the same direction?

When variables in a correlation change simultaneously in the same direction, this indicates a positive correlation. This means that as one variable increases, the other variable also tends to increase. Positive correlations are typically represented by a correlation coefficient that is greater than zero.
