We can see from the table above that all variables are individually significant because thep-values are all smaller than either 5% or 1%. Furthermore, the Fisher probability value is 0.0000, indicating that the model is overall significant at the 1% level. The adjusted coefficient of determination of the regression has a value of 0.6868, indicating that the selected variables explain 68.68 percent of the variability in the endogenous variable. The model calculated exhibits statistical properties of fiability; thus, we conduct a CUSUM sensitivity test to ensure that it is stable over time. The following is the output of the Eviews 8.1 software: Source: Authors computation, using Eviews software Figure 1: CUSUM stability test The figure above indicates that the model's fluctuations curve (shown in blue) does not pass any of the two-tailed 5% test boundaries, indicating that the estimated model is stable. Then,the model's validity is no longer questioned. ii. Relationship between institutions and inflation in Cameroon Verifications before estimation enable us to conduct tests of data fiability (ADF stationarity test) and the existence of a long-term link between the variables picked, in accordancewith econometric rigor (Johansen test). The following are the findings of these tests: Table 5: ADF test INCREASED DICKEY-FULLER STATISTICS VARIABLES AT LEVEL IN FIRST DIFFERENCE DECISION SYSTINS -2,564614 -6,977453*** I(1) TxMASSMO -3,454455 -4,517060*** I(1) TxINF -4,565466 -5.508423*** I(1) TDI -3,547365 -4,256880*** I(1) Source: Computed by authors, using Eviews 8.1 Volume XXII Issue II Version I 36 ( ) Global Journal of Human Social Science - Year 2022 © 2022 Global Journals E Institutional Analysis of the Determinants of Economic Non-Take-Off and High Living Standards in Cameroon between 1990 and 2019
