In GRIDCOPULA: Bivariate Copula Functions Based on Regular Grid

Draws the scatter plot of bivariate data in the unit square

Description

Draws the scatter plot of bivariate data in the unit square

Usage

data.grid(U, draw.lines = TRUE, k = 4, m = 4)

Arguments

U	matrix of size kx2 with the values of both variables.
draw.lines	draws lines inside the unit square or not.
k	positive integer indicating the number of subintervals for the U_2 variable.
m	positive integer indicating the number of subintervals for the U_1 variable.

Value

Returns a scatter plot of bivariate data in the unit square.

Examples

n <- 500
x <- rgamma(n,4,1/2)
e <- rnorm(n,0,.3)
y <- sin(x+e)
Fx <- ecdf(x)
Fy <- ecdf(y)
u <- Fx(x)
v <- Fy(y)
df <- cbind(u,v)
k <- 10
m <- 10
data.grid(U=df, draw.lines = FALSE, k = k, m = m)
data.grid(U=df, draw.lines = TRUE, k = k, m = m)
