This result is not statistically different from the expectation of simple Mendelian segregation of X and Y chromosomes. In essence, such tests are based on whether the observed number of male fetal deaths exceeds the statistically expected value when the unemployment rate moves away from its secular trend and seasonal cycle.
We, of course, cannot randomly assign couples of childbearing age to economies that we can manipulate.

Fisher RA. Owen D, Matthews SG. New issue alert. No one, in other words, would expect the next value of a series to be its mean if previous values exhibited a cycle or trend. We remove remaining patterns in the time series of male fetal deaths by including, as in the decomposition approach, the appropriate lags of the dependent variable among the predictors.
James WH. Best wishes to you. We inspect the residuals of the model for patterns. In sum, these studies indicate male-biased deaths in utero until week 2, then female-biased deaths over the next 4 mo, then little bias for a while, before switching again to male-biased deaths roughly 5 wk before the end of gestation.
