Types of regression and linear regression equation 1. The term regression was first used as a statistical concept in 1877 by Sir Francis Galton. 2. Regression determines ‘cause and effect’ relationship between variables‚ so it can aid to the decision-making process. 3. It can only indicate how or to what extent variables are associated with each other. 4. There are two types of variables used in regression analysis i.e. The known variable is called as Independent Variable and the variable which

Multiple regression‚ a time-honored technique going back to Pearson’s 1908 use of it‚ is employed to account for (predict) the variance in an interval dependent‚ based on linear combinations of interval‚ dichotomous‚ or dummy independent variables. Multiple regression can establish that a set of independent variables explains a proportion of the variance in a dependent variable at a significant level (through a significance test of R2)‚ and can establish the relative predictive importance

the best choice to choose. NGVS are still greatly outnumbered by vehicles‚ which use conventional gasoline. The main reason is that the technology for conventional gasoline vehicles has been developed over many years. However; during the energy crisis period‚ natural gas has become one of the most popular alternative fuels. 3main reasons are environment friendly‚ safety and cheaper price comparing to other gases 1 Environment friendly NGV produce less carbon dioxide or CO2 ✔ NGV is one way
