How does hypothesis testing work in linear regression?
The P value that we see here is the result obtained by performing the above hypothesis test . So while selecting a variable in our LR model we see if the values of “p>|t|” is in acceptance region or not and if the values , usually is grater than 0.002 we remove the variable from the model
When to reject null hypothesis in linear regression?
Make the decision on the basis of the p-value with respect to the given value of β (significance level) Now, if the p-value turns out to be less than 0.05, you can reject the null hypothesis and state that β1 is indeed significant. These Hypothesis testing is also part of the model summary . below is a sample summary of a model
How do you test the intercept in hypothesis testing?
In hypothesis testing you do the same; if you want to show that the intercept (or the slope) is signficantly different from zero, then you assume the opposite, i.e. H 0: β 0 = 0 and try to derive a contradiction from this.
How to calculate confidence intervals for slope and intercept?
An α-level hypothesis test for intercept parameter β0 Conducting hypothesis tests and calculating confidence intervals for the intercept parameter β0 is not done as often as it is for the slope parameter β1. The reason for this becomes clear upon reviewing the meaning of β0. The intercept parameter β0 is the mean of the responses at x = 0.
