Function Documentation

int bootstrap (  double *  cLim1, double *  cLim2, double *  SD, double *  parameter, double *  lowlim, double *  uplim, int  frameNr, double *  tac, double *  fitTac, int  parNr, double *  weight, double(*)(double *)  objf )

Bootstrap method. Original weights are assumed to be inversely proportional to variance. Square root is used, because bootstrap assumes them to be proportinal to standard deviation. If only standard deviation is wanted then cLim1 and cLim2 can be set to be NULL, and if only the confidence limits are wanted then SD can be set to be NULL. Returns: Return values: 0, if ok. 1 - 3 if some of the given parameters is not qualified. 4, if Powell fails, and 5, if out of memory. Parameters: cLim1  vector to put the lower limits to cLim2  vector to put the upper limits to SD  vector to put the standard deviations to parameter  Parameter estimates lowlim  Lower limits for the parameters uplim  Upper limits for the parameters frameNr  Nr of time points in tissue data tac  measured tissue TAC values (will be changed) fitTac  fitted tissue TAC values (preserved) parNr  Nr of parameters weight  weights objf  The object function
