A simple random sample can be taken with or without ________? (Hint this choice will impact how to estimate the variance of the population.) - Replacement In the description of the scientific method from the text which form of causation, sufficient or necessary, specifies that the cause "C" under consideration alone insures occurrence of the effect "E"? - Sufficient according to the authors of the text what are two keys to a successful model? - - Clearly define model objectives (predic...

Linearity/Mean zero assumption - Means that the expected value (deviances) of errors is zero. This leads to difficulties in estimating B0 and means that our model does not include a necessary systematic component Constant variance assumption - Means that it cannot be true that the model is more accurate for some parts of the population, and less accurate for other parts of the populations. This can result in less accurate parameters and poorly-calibrated prediction intervals. response (dep...
