A scalar is a numerical quantity that has a magnitude but no direction.
Definition of Random Forest Random forest: A random forest is a type of decision tree learner that builds a number of decision trees, rather than just one. The individual decision trees are then combined to create the random forest. This approach helps to avoid overfitting the data.
Definition of Oblique Sampling Oblique Sampling: Oblique sampling is a type of non-random sampling technique. It is used when the researcher wants to study a specific population but does not have access to all members of that population. Oblique sampling involves selecting units for the study in a way that is not completely random. The…
Definition of Standard Normal Distribution A normal distribution is a type of distribution that occurs frequently in nature and is symmetrical about its mean. The standard normal distribution is a specific type of normal distribution that has a mean of 0 and a standard deviation of 1.
Definition of Mean Squared Error Mean Squared Error is a statistic used to measure the accuracy of predictions made by a machine learning model. It is calculated by taking the sum of the squared differences between the predicted values and the actual values for each data point, and dividing by the number of data points….
Ad Hoc Analysis is an exploratory analysis technique used to uncover patterns or relationships in a dataset. Often times this work is performed “Ad Hoc” or “On The Fly”… meaning it it done in the moment.
Definition of Quality Control Quality Control: In the context of data science, quality control is the process of ensuring that data is accurate and reliable. This can be done through a variety of techniques, such as checking for inconsistencies, verifying the source of the data, and performing statistical tests. By making sure that data is…
