The most important practical difference between the two is this: Random effects are estimated with partial pooling, while fixed effects are not. Partial pooling means that, if you have few data points in a group, the group's effect estimate will be based partially on the more abundant data from other groups. Sequence. A Sequence is a set of things (usually numbers) that are in order. Each number in the sequence is called a term (or sometimes "element" or "member"), read Sequences and Series for more details. Arithmetic Sequence. In an Arithmetic Sequence the difference between one term and the next is a constant.
The moving range is the difference between consecutive observations. It is expected that the difference between consecutive points is predictable. Points outside the control limits indicate instability. If there are any out of control points, the special causes must be eliminated.

ICA-IMT increase was associated with a family history of CVD among patients aged 15–44 years, and with RF at mid-age. The overall cIMT difference between patients and controls was 12% for CCA, 17% for BIF and 29% for ICA. Further, increased CCA-IMT was associated with male sex and ...
The difference between each term and the next is always 4. This value is called the first difference. So we can continue the sequence by adding 4 each time. This gives the sequence: 7, 11, 15, 19, 23, 27, 31, 35 (b) 1 9 17 25 33 ... 88 88 Here the difference between each term and the next is always 8. To Write out the terms of the following sums; then compute the sum. Example 2. Use sigma notation to express each series. 8 + 11 + 14 + 17 + 20. 8 + 11 + 14 + 17 + 20. This is an arithmetic series with five terms whose first term is 8 and whose common difference is 3. Therefore, a 1 = 8 and d = 3. The nth term of the corresponding sequence is
