21. A polynomial with two indeterminates is called a "'bivariate polynomial " '. 22. Furthermore, the Box Muller transform can be employed for drawing from truncated bivariate Gaussian densities. 23. Galton developed the following model : pellets fall through a bivariate distribution with identical marginal distributions. 24. It may be thought of as an analogue on the torus of the bivariate normal distribution. 25. The length can be calculated based on a bivariate curvilinear regression model using multiple measurement points. 26. In this form, the distribution is a reparameterisation of a bivariate Student distribution with zero correlation. 27. This holds promise provided a regression program is used that allows for both bivariate linear and nonlinear regression. 28. Data classification and graphic representation of the classified data are two important processes involved in constructing a bivariate map. 29. Taught research methods, statistics / computer use, and graduate statistical analysis courses including bivariate and multivariate statistics. 30. Equivalently, this is the graph of the bivariate quadratic equation y = ax ^ 2 + bx + c.
