Seasonal sub-series plots are formed by [3]. Vertical axis: response variable Horizontal axis: time of year; for example, with monthly data, all the January values are plotted (in chronological order), then all the February values, and so on.
By minimizing these systematic variations, true biological differences can be found. To determine whether normalization is needed, one can plot Cy5 (R) intensities against Cy3 (G) intensities and see whether the slope of the line is around 1. An improved method, which is basically a scaled, 45 degree rotation of the R vs. G plot is an MA-plot. [4]

Every rotation in three dimensions is defined by its axis (a vector along this axis is unchanged by the rotation), and its angle — the amount of rotation about that axis (Euler rotation theorem). There are several methods to compute the axis and angle from a rotation matrix (see also axis–angle representation ).
The orientation is usually chosen so that the 90-degree angle from the first axis to the second axis looks counter-clockwise when seen from the point (0, 0, 1); a convention that is commonly called the right-hand rule. The coordinate surfaces of the Cartesian coordinates (x, y, z). The z-axis is vertical and the x-axis is
CeX was started by Paul Farrington, [6] Robert Dudani, [7] Hugh Man, [8] Charlie Brooker, [9] [10] Oli Smith and Oliver Ball. The first shop opened on London's Whitfield Street, close to Tottenham Court Road in 1992. [3] As a second hand retailer, CeX trades with customers offering either cash or a voucher for redemption in any CeX shop. [11]
is the rotation matrix through an angle θ counterclockwise about the axis k, and I the 3 × 3 identity matrix. [4] This matrix R is an element of the rotation group SO(3) of ℝ 3 , and K is an element of the Lie algebra s o ( 3 ) {\displaystyle {\mathfrak {so}}(3)} generating that Lie group (note that K is skew-symmetric, which characterizes ...
