Computes dissimilarities based on the estimated Pearson's correlation of two given time series.

1	diss.COR(x, y, beta = NULL)

`x`	Numeric vector containing the first of the two time series.
`y`	Numeric vector containing the second of the two time series.
`beta`	If not NULL, specifies the regulation of the convergence in the second method.

Two different measures of dissimilarity between two time series based on the estimated Pearson's correlation can be computed. If beta is not specified, the value d_1 = √{ 2 ( 1 - ρ) } is computed, where (ρ) denotes the Pearson's correlation between series x and y. If beta is specified, the function d_2 = √( ((1 - ρ) / (1 + ρ))^β ) is used, where β is beta .

The computed distance.

## Create three sample time series
x <- cumsum(rnorm(100))
y <- cumsum(rnorm(100))
z <- sin(seq(0, pi, length.out=100))
## Compute the distance and check for coherent results
diss.COR(x, y)
diss.COR(x, z)
#create a dist object for its use with clustering functions like pam or hclust
