In statistics and in machine learning, a linear predictor function is a linear function (linear combination) of a set of coefficients and explanatory variables (independent variables), whose value is used to predict the outcome of a dependent variable. This sort of function usually comes in linear … Se mer The basic form of a linear predictor function $${\displaystyle f(i)}$$ for data point i (consisting of p explanatory variables), for i = 1, ..., n, is where Se mer Although the outcomes (dependent variables) to be predicted are assumed to be random variables, the explanatory variables themselves are usually not assumed to be … Se mer • Linear model • Linear regression Se mer An example of the usage of a linear predictor function is in linear regression, where each data point is associated with a continuous outcome … Se mer In some models (standard linear regression, in particular), the equations for each of the data points i = 1, ..., n are stacked together and written in vector form as where Se mer
