quantitative Decision Making - Research Paper Example- the independent and dependent multivariates can be decided incorrectly (in this case it is hard to determine whether change in merchandise intersection of rider cars influences merchandise production of commercial-grade-grade vehicles or vice versa)- the perceived relationship may be a closure of simultaneous influence of the third (moderator) variable on both of the variables separately (for example, correlation between exporting production numbers of passenger cars and commercial vehicles can be explained by the influence of the increase/ hang of the exchange rate on exports of the self-propelled industry in general). It may be true in this case, as the suggested regression model explains hardly 22.2% of variance (R-Squared value is indicated in the table below).Thus, if the export production number of passenger cars increases by 10,000 the export production number of commercial vehicles will go up by 572 (0.0572 coe fficient). The constant 13,002 can be considered rather an anchor tailor for the regression line and should non be taken as the value of JCYF when JCYL is equal to 0 callable to the fact that the data ring available contains no observation with JCYF equals to or is close to 0.To project the export production number of passenger cars (... - the perceived relationship may be a result of simultaneous influence of the third (moderator) variable on both of the variables separately (for example, correlation between export production numbers of passenger cars and commercial vehicles can be explained by the influence of the increase/decrease of the exchange rate on exports of the automotive industry in general). It may be true in this case, as the suggested regression model explains only 22.2% of variance (R-Squared value is indicated in the table below).Linear regression equation JCYF = 13002 + 0.0572 x JCYL (coefficients indicated in the table) multiplexR-SquareAdjustedStErr ofSummary RR-SquareEstimate0.47080.22170.17304184.251262Degrees ofSum ofMean of F-Ratiop-ValueANOVA TableFreedomSquaresSquaresExplained179773016.5679773016.564.55640.0486Unexplained16280127337.917507958.62CoefficientStandardt-Valuep-ValueLowerUpperRegression TableError confineLimitConstant13002.198767187.9038641.80890.0893-2235.47673528239.87425JCYL0.057201630.0267977392.13460.04860.0003929610.1140103Thus, if the export production number of passenger cars increases by 10,000 the export production number of commercial vehicles will go up by 572 (0.0572 coefficient). The constant 13,002 can be considered rather an anchor point for the regression line and should not be taken as the value of JCYF when JCYL is equal to 0 due to the fact that the data set available contains no observation with JCYF equals to or is close to 0.To project the export production number of passenger cars (JCYL), given export of commercial vehicles (JCYF), the JCYF value should simply be blocked into the regression line e quation. The point of estimate number would be
