Code consolidation

I am in the process of writing my first large scale program and I find
myself in the position of writing several copies of functions that do
the same thing, with mostly the same code, but only slightly different.
For example:

double
Chisqrd1(double *params, double *weight) { // CHANGE
int i;
double deltay, chiSqrd;
xy_t *data;

chiSqrd = 0.0;
data = dataList;
for (i = 0; data != NULL; i++) {
deltay = data->y - netCarriers(params, data->x); // CHANGE
chiSqrd += weight[i] * deltay * deltay;
data = data->next;
}
return(chiSqrd);
}

double
Chisqrd2(dopant_t *dopants, double *weight, double *Ef, double Eg) { //
CHANGE
int i;
double deltay, chiSqrd;
xy_t *data;

chiSqrd = 0.0;
data = dataList;
for (i = 0; data != NULL; i++) {
deltay = data->y - netIonized(dopants, data->x, Ef[i]); // CHANGE
chiSqrd += weight[i] * deltay * deltay;
data = data->next;
}
return(chiSqrd);
}

I was wondering if there are common ways to cut down on this type of
duplication without adding too much to the overall complexity. Does
anybody have any suggestions? Thanks.
