Estimates the percentage of similarity of two univariate signals Y (imputed values) and X (true values).

Y |
vector of imputed values |
X |
vector of true values |
This function returns the value of similarity of two vectors corresponding to univariate signals. A higher similarity (Similarity \in [0, 1]) highlights a more accurate method for completing missing values in univariate datasets. Both vectors Y and X must be of equal length, on the contrary an error will be displayed. In both input vectors, eventual NA will be excluded with a warning diplayed.

# By definition, if true values is a constant vector

# similarity = 1.
