N2 - Light variations of the representative sample of 26 more or less periodically variable carbon stars were analyzed on the base of their 2220 individual observations made by Hipparcos satellite and 33 544 visual observations listed in AFOEV and VSOLJ databases within the interval JD 2 448 000(1988)+/-6 cycles. We found the osculating linear ephemerides of all stars and their mean light curves, as well. We found that light curves of the carbon Miras in our set can be satisfactorily expressed as a linear combination of only two basic light curves. The analysis was done by an own method combining robust regression and principal component analysis.
