Draws a double-headed arrow.
Syntax
result = pd.Cov (variable1, variable2)
result = pd.Cov (variable1, variable2, covarianceValue)
result = pd.Cov (variable1, variable2, covarianceName)
result = pd.Cov (variableName1, variableName2)
result = pd.Cov (variableName1, variableName2, covarianceValue)
result = pd.Cov (variableName1, variableName2, covarianceName)
The Cov method syntax has the following parts:
Part |
Description |
result |
(Object of type PDElement) The new double-headed arrow. |
variable1, variable2 |
(Objects of type PDElement) The two variables to be connected by the new double-headed arrow. |
variableName1, variableName2 |
(Strings) Names of the two variables to be connected by the new double-headed arrow. |
covarianceValue |
(Double) The value of the covariance represented by the new double-headed arrow. |
covarianceName |
(String) A name for the covariance represented by the new double-headed arrow. |
Remarks
If you do not specify a name or value for the covariance represented by the double-headed arrow, the covariance will be unconstrained.
