D5) Consider the logistic regression model P(Y=1) = 1 /( 1 + exp(-(a+bx))) where a = 1, b = 1.5 and the errors are normally distributed with mean 0 and standard deviation 1. Let x be a sequence from -4 to 4 in increments of 0.1. Estimate the bias of the slope for a simple linear regression model at x = 0 compared to the true slope (change in probability over change in x) of the logistic function at x = 0

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
