The new shape visualizes the results regarding street analyses. Quantity on arrows inform you standardized parameter prices. Connections having p opinions not as much as 0.05 is actually marked from the “*”, people with p thinking around 0.01 was noted by “**”, and the ones with p philosophy not as much as 0.001 is actually marked of the “***”.

In the future training, such grounds will likely be checked out on the an older Czech people take to.
