JML

• Joint Maximum Likelihood(JML) Method

import numpy as np
import pandas as pd
import girth
df = pd.read_csv("https://github.com/jmnote/zdata/raw/master/github.com/cran/ltm/data/LSAT.csv")
m = np.transpose(df.values)
estimates = girth.twopl_jml(m)
pd.DataFrame(estimates)

MML

• Maximum Marginal Likelihood(MML) Method

import numpy as np
import pandas as pd
import girth
df = pd.read_csv("https://github.com/jmnote/zdata/raw/master/github.com/cran/ltm/data/LSAT.csv")
m = np.transpose(df.values)
estimates = girth.twopl_mml(m)
pd.DataFrame({k: estimates[k] for k in ('Discrimination','Difficulty')})
