The estimation process begins by assuming or hypothesizing that the least squares linear regression model (drawn from a sample) is valid. The formal twovariable linear regression model is based on the following assumptions: (1) The population regression is adequately represented by a straight line: E(Yi) = μ(Xi) = β0 + β1Xi (2) The error terms have zero mean: E(∈i) = 0 (3) A constant variance (homoscedasticity): V(∈i) = σ2

Threshold regression models are a diverse set of nonregular regression models that all depend on change points or thresholds. They provide a simple but elegant and interpretable way to model certain kinds of nonlinear relationships between the outcome and a predictor.

Temperature is the most important factor in regulating the germination of nondormant seeds at the beginning of the growth season. The present study was conducted to produce simple regression models to predict how temperature affects the time it takes for 50% of a selection of flax seeds to germinate.

Multiple regression is the extension of simple regression, to take account of more than one independent variable X. In multiple regression, we study the relationship between Y and a number of explanatory variable (X1, X2, …, Xk). The model we assume is as follows: Yi = β0 + β1X1 + β2X2 + … + βkXk + ei

We assessed the factors relating to the prevention of the Novel Coronavirus Disease (COVID19) for students at the University of Medicine and Pharmacy at Ho Chi Minh City, Vietnam. Methods: A crosssectional study was performed in February and March 2020. A 21 item selfadministered questionnaire on the knowledge, attitude, and practices regarding COVID19 was collected from students of the first to the sixth year using the strategy of simple random sampling.

Given a collection of records (training set ) Each record contains a set of attributes, one of the attributes is the class. Find a model for class attribute as a function of the values of other attributes. Goal: previously unseen records should be assigned a class as accurately as possible. A test set is used to determine the accuracy of the model. Usually, the given data set is divided into training and test sets, with training set used to build the model and test set used to validate it.
