WebLinear regression is a statistical method used in Machine Learning for predictive analysis, it is used to predict the value of a variable based on the value of another variable. In the model below, I have analysed some data and I have trained an AI and Machine Learning model using test data to predict whether y is dependent on x. Webregression model the null hypothesis is always a simple hypothesis. That is to say, in order to formulate a null hypothesis, which shall be called H 0 , we will always use the operator “equality”. Each equality implies a restriction on the parameters of the model. Let us look at a few examples of null hypotheses concerning the regression model:
