But these particular findings are only preliminary, on about 30 babies aged between four and nine months. We are collecting more data, she said.
Linear regression attempts to model the relationship between two variables by fitting a linear equation to observed data. One variable is considered to be an explanatory variable, and the other is considered to be a dependent variable.
Given a relation in x and y, if to each value of x in the domain there corresponds. exactly one value of y in the range, then y is said to be a function of x. In the previous deânition, since y depends on x, we call x the independent variable and the y the dependent variable.
