Why the covariance is negative?
Covariance indicates the relationship of two variables whenever one variable changes. Decreases in one variable resulting in the opposite change in the other variable are referred to as negative covariance. These variables are inversely related and always move in different directions.
Is a negative covariance good?
Covariance is a statistical measure of how two assets move in relation to each other. A negative covariance indicates that two assets move in opposite directions. In the construction of a portfolio, it is important to attempt to reduce the overall risk and volatility while striving for a positive rate of return.
Is it possible to get a negative variance in Amos?
The following variances are negative. Although variances cannot be negative, Amos can produce variance estimates that are negative. The solution is then called inadmissible. Negative variances and R-squared values greater than 1 are not theoretically possible, so the solution is considered improper and the other estimates are not reliable.
Which is not the strongest covariance in Amos?
When analyzing the estimated covariances in AMOS the problematic one has .55 and is not the strongest covariance. One of the two problematic latent constructs has a covariance of .60 with another latent construct.
Do you have to have more than 2 manifest variables in Amos?
In the context of confirmatory factor analysis, the implication is that it is preferable to have more than 2 manifest variables defining a latent variable. It is not mandatory and there are several examples in the AMOS User’s Guide of latent variables that are defined by only 2 observed variables.
What is the covariance between latent constructs above 1?
Total N is 308. The SEM shows a covariance between two of the latent constructs above 1 when standardized. However, when I run bivariate correlation analysis of the seven constructs in SPSS (as manifest variables off cause) the correlation between this pair is .71.
