Children are exposed to many colours in their environment Some babies show a striking preference for just one colour, while others will like a few colours. 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.
To determine if an equation describes a function, identify the independent and dependent variable. Now determine if each value of the independent variable selected from the domain of the correspondence matches with no more than one value of the dependent variable. If there is no more than one match, then the correspondence is a function.
