Bivariate Student-t Distribution Cumulative Distribution Function
Density for the bivariate Student-t distribution distribution.
dbistudentt(x1, x2, df, rho = 0, log = FALSE)
x1, x2 |
vector of quantiles. |
df, rho |
vector of degrees of freedom and correlation parameter.
For |
log |

One can think of this function as an extension of
dt to two dimensions.
See bistudentt for more information.
dbistudentt gives the density.
