Abstract: | A new modification of the least squares method (LSM) is proposed. The main idea is to consider the fitting parameters β
i
as independent random variables with a certain distribution density F(β1, β2, ..., β
k
; φ1, ..., φ
m
), which depends on a set of m experimental points φ
j
. Within this approach, the estimates of the parameters minimize squared deviations and are equivalent to means of the probability distribution = = ∫β
