Data processing for radioimmunoassay standard curve using microcomputer: a new BASIC program for weighted logit-log transformation.
A new BASIC program of the weighted linear, quadratic and cubic logit-log regression methods for data processing of radioimmunoassay standard curve was developed using a microcomputer. Using this program, three regression analyses are calculated and the table for root mean square of residuals in each regression are shown for the selection of the regression method. The data of three radioimmunoassays of human pancreatic enzymes and pancreatic secretory trypsin inhibitor were examined by this program and compared with those processed by the four parameter logistic method. The weighted cubic logit-log regression showed better fit in radioimmunoassays of human pancreatic enzymes with larger molecular weights. The present program is useful and practicable for its simplicity and accuracy.
