Function PAGE computes the value of Page test statistic for layout matrix x, with subjects in rows and treatments in columns. Midranks are calculated with Matlab's TIEDRANKS.
Function MCPAGE computes the value of Page test statistic for layout x and B random within-subject permutations of x, aiding a Monte Carlo approximation of an 'exact' test significance level. See the function's help header for an example.
The submission considers first-order exponential-decay Hawkes processes with constant unconditional intensities, and presents
a) a calculation of point-time intensities for constituent series of a multivariate process;

CFEVALDEMO2 illustrates how CFEVAL (available from FEX) can be used to model a mortgage, a mortgage passthrough, or a collateralized mortgage obligation.
To run the code, you will need to download the FEX submissions listed in...
Functions NELSONFUN and NELSONFIT evaluate and fit (with non-linear least-squares) the Nelson-Siegel function, a popular yield-curve approximation device.
Function CIRPATH simulates a discretely-sampled path of a Cox-Ingersoll-Ross process.

Function HISTF ('flexible histogram') extends Matlab's HIST by letting one bound displayed percentiles, set x-axis limits and y-axis maximum, set x bin size, and draw a marker line at given x position. In contrast to HIST, relative rather than...
