Run a Paired Samples t Test. To run a Paired Samples t Test in SPSS, click Analyze Compare Means Paired-Samples T Test. The Paired-Samples T Test window opens where you will specify the variables to be used in the analysis. All of the variables in your dataset appear in the list on the left side.
A fixed point is a point that does not change upon application of a map, system of differential equations, etc. In particular, a fixed point of a function f(x) is a point x_0 such that f(x_0)=x_0. (1) The fixed point of a function f starting from an initial value x can be computed in the Wolfram Language using FixedPoint[f, x].
We define the fixed point index of f at z0, denoted i(f, z0), to be the multiplicity of the zero of the function f(z) â z at the point z0. In real Euclidean space, the fixed-point index is defined as follows: If x0 is an isolated fixed point of f, then let g be the function defined by.
