Although it is known that ART / IVF miscarriage rate increases with advancing age, the recent study showed that miscarriage rate is higher not only in older but also in very young women, albeit to a lesser extent, with miscarriage rate declining steadily to age 28 and increasing steadily thereafter in a u-shaped curvilinear regression. "What that means is that," Dr.
To predict the chicken age, a curvilinear regression was fitted using the following equation
The discovery of the precise relation between two or more variables is a problem of curve fitting known as 'non-linear' or 'curvilinear regression' and the fitting of a straight line to data is the simplest case of this general principle.
