Technically, in time series forecasting terminology the current time (t) and future times (t+1, t+n) are forecast times and past observations (t-1, t-n) are used to make forecasts.We can see how positive and negative shifts can be used to create a new DataFrame from a time series with sequences of input and output patterns for a supervised learning problem. import statsmodels.api as sm X_train_sm = sm.add_constant(X_train) logm2 = sm.GLM(y_train,X_train_sm, family = sm.families.Binomial()) res = logm2.fit() res.summary() y_train_pred = res.predict(X_train_sm) #Predict blood sugar level Step 5: Predict Diabetes.
