which is better gamble or restricted model what is restriction of lm3 in r what is f test used for in r can you test two linear models using an f test and bootstrap method? lm3 is a full model whereas lm4 is a restricted model. what is the limit to an r test can you test for multiple linear restrictions in r which model of regression is better how to test multiple linear restriction models which model is better for restricted data how to do an f test for linear restrictions when do you bootstrap a linear model which is better a full or restricted r model? how to test a linear restriction which model is better the full or restricted model? how to test if a model is more restrictive than another what model is used to test multiple regressions which is better model than full model which type of model is best for an r test what is the difference between lm4 and lm3 in r
