NettetWhen setting up a linear model, we can use either form for the equation of a line, but most of the time we will use the slope-intercept form: y = mx + b. Understanding Word Problems In order to set up a model, it is important to be able to decipher what the information you are given in a word problem represents. Simple linear regression is a parametric test, meaning that it makes certain assumptions about the data. These assumptions are: 1. Homogeneity of variance (homoscedasticity): the size of the error in our prediction doesn’t change significantly across the values of the independent variable. 2. Independence of … Se mer To view the results of the model, you can use the summary()function in R: This function takes the most important parameters from the linear model and puts them into a table, which looks like this: This output table first … Se mer No! We often say that regression models can be used to predict the value of the dependent variable at certain values of the independent variable. However, this is only true for the … Se mer When reporting your results, include the estimated effect (i.e. the regression coefficient), standard error of the estimate, and the p value. You should also interpret your numbers to make it clear to your readers what your … Se mer
