regression_elimination

Evaluation of the liminf or the limsup of the quotient yn/xn with successive eliminations

Syntax
[a,b]=regression_elimination(x,y,SupOuInf,Sigma,Gamma,TolNum)

Inputs

x : Abscissas

y : Ordinates

SupOuInf : 'lsup' for limsup, 'linf' for liminf.

TolNum, Sigma, Gamma :
The point n is eliminated if y(n)+TolNum+Sigma*sqrt(N)*n^Gamma is inferior to the value of the regression line at x(n)

Outputs

a :Slope of the last line, evaluation of the liminf or the limsup.

b :Value of the last line at x=0 : offset
