Linear Predictive Coding (LPC) is a method for estimating the coefficients of a Source-Filter model (post) from a given data. The input consists of a time-series representing amplitudes of speech collected at fixed intervals over a period of time. NettetWhen using lm(), even if not a factor, R would have treated x1 as such. Coercion to factor is more important if a categorical variable is coded for example as 1, 2 and 3. Otherwise it is treated as numeric, which creates a difference in the regression model. The following two models illustrate the effect of factor variables on linear models. do birds mate with their siblings
