To overcome this problem a novel method based on linear regression model is proposed which improves the prediction accuracy along with speed, named CRLRM (Category based Recommendation using Linear Regression Model). Performance of our method is evaluated by MAE and show 30-40% improvement in number of rating out of 100000 rating.An introduction to simple linear regression Regression models describe the relationship between variables by fitting a line to the observed data. Linear regression models use a straight line, while logistic and nonlinear regression models use a curved line.Simple linear regression was carried out to investigate the relationship between gestational age at birth (weeks) and birth weight (lbs). The scatterplot showed that there was a strong positive linear relationship between the two, which was confirmed with a Pearson’s correlation coefficient of 0.706. Simple linear regression showed a significant.

A simple linear regression is carried out to estimate the relationship between a dependent variable, Y, and a single explanatory variable, x, given a set of data that includes observations for both of these variables for a particular population.

Linear regression looks at a relationship between the mean of the dependent variable and the independent variables. For example, if you look at the relationship between the birth weight of infants and maternal characteristics such as age, linear regression will look at the average weight of babies born to mothers of different ages.

Linear regression is a kind of statistical analysis that attempts to show a relationship between two variables. Linear regression looks at various data points and plots a trend line. Linear regression can create a predictive model on apparently random data, showing trends in data, such as in cancer diagnoses or in stock prices.

Assignment 2: LASA 1: Linear Regression In this assignment, you will use a spreadsheet to examine pairs of variables, using the method of linear regression, to determine if there is any correlation between the variables. Afterwards, you will postulate whether this correlation reveals a causal relationship (and why).

Regression Analysis: presupposes that a linear relationship exists between one or more independent (casual) variables, which are predicted to affect the dependent(target) variable.
