WitrynaLogistic Regression is an easily interpretable classification technique that gives the probability of an event occurring, not just the predicted classification. It also provides a measure of the significance of the effect of each individual input variable, together with a measure of certainty of the variable's effect. http://www.duoduokou.com/python/27553860657151403083.html sandwich panel installation method statement
