set of data. Specifically, given a set of measurements on two random variables, y and x, regression provides a means for finding the values of the coefficients a and b for the straight line (y = a+ bx) that best fits the data. The coefficients a and b can be found using least square method using the following two equations simultaneously

Managing Commercial Building Pressurization

Infiltration of warm, moist air also affects occupied spaces by increasing latent loads. Conditioned indoor air leaks out of— exfiltrates from—the building when the pressure inside is greater than the pressure outside. During the summer, exfiltration of cool, dehumidified indoor air benefits the building by keeping the envelope dry.
