How to do Dose/Response curve fitting in Python for Drug Discovery

doseResponsePython.ipynb

I am getting this error. I checked and found that there is no plt.plot in seaborn.
sns.plt.plot([pDose(i) for i in refDose],[ll4(i,*[fit[i] for i in ['b','c','d','e']]) for i in refDose])
AttributeError: 'module' object has no attribute 'plt'

import matplotlib.pyplot as plt is missing from the imports
and
sns.plt.plot needs to be modified to plt.plot

for fit in fitData:
plt.plot([pDose(i) for i in refDose],[ll4(i,*[fit[i] for i in ['b','c','d','e']]) for i in refDose])

Thanks! Fixed the code as you suggested, should work now @akashbahai @cbmII

How would you go about implementing a 1/Y^2 weighting and returning their parameter values as well as visualising the line on the graph?

Hey @Fae14, this link should give you a few pointers:

Hope this helps!

Nice attempt. May be code should be more explanatory and have more comments,

Copied as-is into a new jupyter session, I get the following after assigning fitCompound:

Then a type error making the lmplot:

I have the same problem, anyone found a solution?

@resminer @meeuosh thanks for your patience, the last commit should solve the issue (mixing positional and named arguments is never a good idea!)
