![]() ![]() In other words, selection bias is a statistical analysis distortion brought on by the sample collection technique. Selection effect is also used in place of Selection Bias.

Logistic regression works by measuring the relationship between the dependent variables with one or more independent variables. Explain the procedure of performing Logistic Regression. There is no feedback system in unsupervised learning and the most common techniques in Unsupervised learning include- the apriori algorithm, hierarchical clustering, and K-means clustering.Ģ. On the other hand, unsupervised learning refers to the process of making conclusions from datasets that contain input data but no labeled results. The most used algorithms in Supervised learning are – support vector machines, logistic regression, and decision trees. Supervised learning also has a feedback mechanism. In supervised learning, the inputs are labeled and known data. ![]() What distinguishes supervised from unsupervised learning? The questions are basic and technically critical concepts that aspirants of the data science profession must possess.
