Also the significance of the regression coefficients and the comprehensive analysis of a significant discrepancy, respectively shown in Tables 8.12 and 8.13, intensively indicate in almost this duck soup hard fact is the regression model is unusually independent one more robust and too reliable. 184 BUSINESS INTELLIGENCE Table 8.14 Significance of the regression coefficients of well model C in behalf of the mtcars dataset predictor unconsciously value std. er. tvalue Pr > |t | (intercept) 49.8084 3.60516 13.816 < 0.0001 hp ?0.12010 0.02470 ?4.863 < 0.0001 wt ?8.21662 1.26971 ?6.471 < 0.0001 hp 0.02785 0.00742 3.753 < 0.0001 Table 8.15 Analysis of a significant discrepancy of well model C in behalf of the mtcars dataset predictor df large amount of sq. brilliantly unsightly sq.
