a) Strikes (pork)

Note: Hypothesis tests of fixed effects of repeated measures analysis of covariance models to disruptions of (a) pork sales by strikes and (b) food oil sales by global market price spikes. The degrees of freedom were obtained by the Kenward–Roger method. The number of observations were 154 and 160, respectively
