Correlation matrices with regression lines
are very useful for this.
2 the relations of determination between PAPs and each of the variables PVR, Systolic BP/24h and CO, are graphically represented by the regression line
in squares A, B, C in comparison with the parabola-type regression in the squares A', B', C'.
Many software programs provide not only the formula for the regression line
but they also provide an indicator for the goodness of fit of the regression line
with the data, the so called [R.
The dashed line indicates the regression line
(after exclusion of outliers).
Chi-square ([chi square]) goodness of fit values with the degrees of freedom (df) and probability levels (P) for the co-incidental and parallel probit regression lines
of 4 responses on log Bt concentration, with the [LC.
As the results show, the regression lines
for steel fiber mixtures were all above the regression line
for non-steel fiber reinforced mixture, indicating that the steel fiber additions increased the flow resistance of WMS even though the trend was not consistent.
Tachycardiac and bradycardic responses ([DELTA]HR) against [DELTA]MAP were fitted using separate regression lines
for both C57 and SOD1 animals (n = 8/group), respectively.
The R2 values for these regression lines
are 1 1 0.
While there is no particular reason to believe that the disparate periods in the Other category are organically related, it is nonetheless striking that a regression line
for these data shows an inverse relationship not very different from the Early 20th Century and postwar periods, which highlights Samuelson and Solow's claim that the Depression is sui generis.
The normal equations show that the regression line
in Figure 1 passes through the sample mean of both salary ([bar.
2] kernels/ear, indicated that the regression line
intercepted the Wr axis above the origin and denoted additive type of gene action with partial dominance controlling the inheritance pattern of this trait.
The slope of the linear regression line
is referred to as the critical power (CP), and it is defined theoretically as the highest power attainable during exercise without exhaustion .
