A logit regression program in Excel

<-- Back to calibration programs

This logit regression program is optimised to work with ELISA-data but can be used with all sigmoid curves until a straight line.
Read the instructions carefully on the TAB-sheet instructions
The program let you choose:
- the number of significant digits in the result,
- it calculates a average of the results,
- it warns in red when a results deviates more then a give percentage from the mean,
- and many more


Advise (thumb rules)
:
Do not use more than 5 doses and one blank. (This logit needs a blank! (zero dose)). If you want to use more data points invest in multiplos instead of more doses.
The lowest point of the curves must be higher than 10 times the standard deviations of the noise in your blank
The highest point of your curves should be 10% higher in response than the second highest response.
Do not copy, move and paste in the worksheet. If the program does not work properly use a new clean copy of it.
