Merge branch 'master' of https://github.com/swirldev/swirl_courses
custom test equiv_val to check for equivalent values
Clarifying a question. Will add test for variable "fit" creation later when I have time to test.
Custom test, creates_lm_model, fails to catch misnamed model. Used additional test expr_creates_var as a temporary fix. Origin of custom test problem is not obvious.
moved playing card questions along with cards.R to probability1 lesson
forgot to save changes to prob1/lesson file
Merge branch 'master' into statinf
Fixed bug causing failure of custom test, creates_lm_model, to catch incorrectly named models. This test is used in other lessons. I will fix there and test as time permits.
Add corrected custom test `creates_lm_model` to Residuals, Diagnostics and Variation and to Residuals (to address issue of thread 58, regmods-006, swirl assignment forum). Tested both lessons.
Updated custom test for linear models to bugfixed version in 5 Regression Models lessons. Tested changes.
Correct minor bug in creates_glm_model which the test inherited from its predecessor, creates_lm_model.
more work on prob2 lesson
