3.4. ANALYSES 75<br />
3.4 Analyses<br />
This section presents the analyses. I analyse the noise-reducing effect of RPE with structural<br />
equation modelling (SEM). I use the structural model estimation of SEM to be able<br />
to estimate the indirect relation between environmental uncertainty and noise in the performance<br />
evaluation, via RPE use.<br />
In addition to the aforementioned noise-reducing effect of RPE use and the effect of environmental<br />
uncertainty, via RPE use, on noise, I include the noise-drivers and control<br />
variables for size and industry. The result is the statistical model shown in figure 3.3.<br />
3.4.1 Correlations<br />
Table 3.9 presents the correlation matrix of all of the included variables. The table shows<br />
three significant correlations between the dependent and independent variables. Noise is<br />
negatively correlated with RPE-Use. Additionally, the correlations among noise and goal<br />
ambiguity, and noise and measurability of outputs are significant. The latter two correlations<br />
are consistent with the hypothesized directions. Furthermore, several significant<br />
correlations among the independent variables exist. RPE-Use is positively correlated with<br />
environmental uncertainty, and measurability of outputs. Additionally, I find significant<br />
correlations between the measures of goal ambiguity and measurability of outputs, as well<br />
as between the measures for business unit size and firm size. However, these correlations<br />
are not strong.<br />
3.4.2 Multivariate Analyses<br />
To test the noise-reducing effect of RPE, I analyse the model that is presented in figure 3.3.<br />
In addition to the expected paths, as presented in the causal model (figure 3.2 on page 66),<br />
I also include the control variables for size and business unit sector in the model. I use maximum<br />
likelihood estimation in AMOS 18 to estimate the structural model. Due to sample<br />
size limitations and to reduce the model complexity, I do not estimate the measurement<br />
model and the structural model simultaneously. The measurement is determined outside<br />
the model, using principal component analysis and scale reliability analysis, as presented<br />
in section 3.3.3.<br />
I run two analyses. First, the model is tested with the RPE-Use measure. This model<br />
is referred to as the base model. Second, an alternative measure for RPE use is used as<br />
a robustness check. Both models fit the data and support the noise-reduction hypothesis<br />
(i.e., RPE use reduces the amount of noise in the performance evaluation). The results<br />
of these analyses are discussed in section 3.4.2.1. ‘Analyses with RPE-Use Measure’ and<br />
section 3.4.2.2. ‘Analyses with RPE-based-Targets Measure’.
