Refer to the lab output on neural network model fits on the bankruptcy data. https://yanyudm.github.io/Data-Mining-R/lecture/9.A_NeuralNet.html We now fit a glm (model 1), neural network with “hidden=c(3)” (model 2), and neural network with “hidden=c(5)” (model 3) to the bankruptcy data.  We have 10 financial ratios as the predictors (X). The response (Y) is binary, 1=bankruptcy, 0=non-bankruptcy.read.csv(file = “https://yanyudm.github.io/Data-Mining-R/lecture/data/bankruptcy.csv”, header=T) Note that in the output layer, there is only ONE class where DLRSN (deletion reason)=1 is bankruptcy, and DLRSN=0 is nonbankruptcy as a reference class. How many parameters are involved for the neural network model with “hidden=c(5)”?
