Use regression analysis to examine the variation in a dependent
variable. Use 0.05 level of significance unless other
stated.
When doing various tests (fit, significance) report the
relevant values of the parameters (test stats, R square)
Make sure to write out your hypotheses and rejection rules for
significance tests. If p-values are greater than 0
report the level at which your test is significant.
Conclusions are to be in terms of the problems; pretend the
reader has no idea about you were...
