WitrynaLogistic regression finds the weights 𝑏₀ and 𝑏₁ that correspond to the maximum LLF. These weights define the logit 𝑓 (𝑥) = 𝑏₀ + 𝑏₁𝑥, which is the dashed black line. They also define the predicted probability 𝑝 (𝑥) = 1 / (1 + exp (−𝑓 (𝑥))), shown here as the full black line. Witryna31 lip 2024 · Determining Sentiment. We can utilize a library such as “TextBlob.Sentiment” to calculate the sentiment of each review but since we have the actual employee rating we can use this column instead. The employee rated the company on a 5-point Likert Scale and over 75% of the ratings are positive (ie. 5 or 4).
