375 1 8. 1. The histogram and the qq plot are telling you the same story. You have heavier tails than in a normal. That means higher bars in the tails of a histogram and steeper slopes in the tails of the qqplot. Otherwise your distribution is close to symmetric. That's a pretty normal (common) kind of non-normal (non-Gaussian) distribution.

The residuals are essentially the difference between the predicted value and the actual value (i.e. the 'error' in your predicted value) .
The q-q plot selects quantiles based on the number of values in the sample data. If the sample data contains n values, then the plot uses n quantiles. Plot the ith ordered value (also called the ith order statistic) against the i − 0.5 n th quantile of the specified distribution. Here are the histograms of the samples used to plot the q-q-plots. Notice how heavy-tails, light-tails, and di erent types of skew a ect the q-q-plots.
